Cevap: True

Cevap

The overall evaluation is True because Statement I is False, Statement II is True, and Statement III is True.

Evaluating all three statements shows that Statement I is False (

90.0\% \ngtr 90.5\%

), Statement II is True (

0.408 > 0.40

), and Statement III is True (

4

zones meet both criteria). Thus, the proposed outcome (False, True, True) accurately describes the dataset.

,

91.0\%

,

92.5\%

. Median =

\frac{89.0\% + 91.0\%}{2} = 90.0\%

. Since

90.0\% \le 90.5\%

, Statement I is False.

Determines whether Statement I is correctly classified as False.

2

Evaluate Statement II by identifying the three zones with the minimum unplanned maintenance hours and computing their aggregate discharge per MWh of capacity.

Fewest maintenance hours: Zone Beta (

12\text{ hrs}

), Zone Zeta (

18\text{ hrs}

), Zone Delta (

24\text{ hrs}

). Sum of energy discharged =

84.0 + 105.0 + 117.0 = 306.0\text{ GWh}

. Sum of capacity =

200 + 250 + 300 = 750\text{ MWh}

. Rate =

\frac{306.0}{750} = 0.408\text{ GWh/MWh}

. Since

0.408 > 0.40

, Statement II is True.

Determines whether Statement II is correctly classified as True.

Based on the table, evaluate the following statement:
"The median Q1 electricity consumption of branches in the North region is greater than the median Q1 electricity consumption of branches in the South region."

Is this statement True or False?

Doğru

Yanlış

Cevabı ve açıklamayı göster

Cevap: False

Cevap

The statement is False. The median Q1 electricity consumption for branches in the North region (

10,500\text{ kWh}

) is less than the median Q1 electricity consumption for branches in the South region (

14,500\text{ kWh}

).

The evaluation shows that the median Q1 value for the North region (

10,500\text{ kWh}

) is strictly less than the median Q1 value for the South region (

14,500\text{ kWh}

). Therefore, the assertion that North is greater than South evaluates to False.

Adım Adım Çözüm

1

Identify Q1 consumption figures for branches in the North region and calculate their median.

Branches in the North region are Alpha (

12,000\text{ kWh}

) and Gamma (

9,000\text{ kWh}

). The median is

\frac{12,000 + 9,000}{2} = 10,500\text{ kWh}

.

Filtering rows by the condition 'Region = North' isolates the correct values for statistical evaluation.

2

Identify Q1 consumption figures for branches in the South region and calculate their median.

Branches in the South region are Beta (

18,000\text{ kWh}

) and Zeta (

11,000\text{ kWh}

). The median is

\frac{18,000 + 11,000}{2} = 14,500\text{ kWh}

.

Filtering rows by the condition 'Region = South' isolates the comparison dataset.

3

Compare the two median values to evaluate the boolean statement.

Comparing

10,500\text{ kWh}

to

14,500\text{ kWh}

shows that

10,500 < 14,500

, making the statement false.

The statement claims North is greater than South, which contradicts the calculated result.

Cevabı ve açıklamayı göster

Cevap

Statement I matches with True (West region average is 12.5 hours); Statement II matches with True (Gamma has highest shipments and lowest delivery rate); Statement III matches with False (3 out of 6 is exactly half, not more than half).

Each statement is evaluated against the data in the table: Statement I evaluates to True because the average for West warehouses (12.0 and 13.0) is 12.5 hours. Statement II evaluates to True because Gamma holds both the maximum shipment volume (15,200) and minimum delivery rate (91%). Statement III evaluates to False because exactly 3 out of 6 warehouses (50%) have delivery rates above 94%, which does not exceed half.

Adım Adım Çözüm

1

Evaluate Statement I by filtering by Region = West.

Beta (12.0 hrs) and Epsilon (13.0 hrs) are in the West. Average = (12.0 + 13.0) / 2 = 12.5 hours. 12.5 < 13.0 is True.

Calculate the mean value of processing time for the specified subset.

2

Evaluate Statement II by identifying the maximum shipment count and minimum delivery rate.

Maximum shipments = 15,200 (Gamma). Minimum delivery rate = 91% (Gamma). The condition holds True.

Determine if both extreme statistical properties apply to the same entity.

3

Evaluate Statement III by filtering for delivery rates > 94%.

Beta (96%), Delta (98%), and Epsilon (95%) qualify (3 warehouses). 3 out of 6 equals 50%, which is not > 50%. The statement is False.

Compare the count of matching rows against the threshold 'more than half' (strictly greater than 50%).

Statement: For more than half of the divisions listed, the Revenue per employee strictly exceeds $250,000.

Doğru

Yanlış

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True. Exactly 3 out of the 5 divisions (Alpha, Gamma, and Delta) have a Revenue per employee greater than $250,000, which satisfies the condition of being more than half.

The correct evaluation is True because calculating the ratio of Revenue to Employees for each of the five divisions shows that Alpha (

266,667), Gamma (

320,000), and Delta (

300,000) all have a Revenue per employee above

250,000. Three out of five divisions represents 60% of the divisions, which is more than half.

Adım Adım Çözüm

1

Understand the condition and metric required

Need to calculate Revenue per employee (Revenue in dollars divided by number of employees) for each division and check if it is strictly greater than $250,000.

The statement specifies 'strictly exceeds $250,000' and applies to 'more than half' (at least 3 out of 5) of the divisions.

2

Compute Revenue per employee for each division

Alpha:

120M / 450 =

266,667; Beta:

200M / 800 =

250,000; Gamma:

80M / 250 =

320,000; Delta:

150M / 500 =

300,000; Epsilon:

300M / 1,200 =

250,000.

Performing explicit division allows precise comparison against the threshold value of $250,000.

3

Evaluate the threshold condition across all divisions

Divisions exceeding

250,000: Alpha, Gamma, Delta (Total = 3 divisions). Divisions equal to

250,000: Beta, Epsilon (Total = 2 divisions).

Values exactly equal to $250,000 do not satisfy 'strictly exceeds'.

4

Determine overall Boolean truth value

3 out of 5 divisions is 60%, which is more than half (50%). Thus, the statement evaluates to True.

Comparing the count of meeting divisions (3) against half of the dataset size (2.5).

Cevap

Statement 1 matches the evaluation confirming it is True (

2.40 > 2.2026

); Statement 2 matches the evaluation confirming it is False because

165 > 113.33

; Statement 3 matches the evaluation confirming it is False due to C-South failing the conditional threshold.

Each statement matches its precise evaluation. Statement 1 correctly identifies that the median cost per trip (

2.40

) exceeds the weighted average system cost (

2.2026

). Statement 2 identifies that the mean fleet size for high zero-emission corridors (

165

) is higher, not lower, than for low zero-emission corridors (

113.33

). Statement 3 correctly identifies that C-South is excluded altogether because its on-time departure rate is

85\%

, below the required

88\%

threshold.

Adım Adım Çözüm

1

Calculate the median operating cost and system-wide weighted average operating cost for Statement 1.

Corridor operating costs in ascending order:

\$1.80, \$1.95, \$2.20, \$2.40, \$2.60, \$2.85, \$3.10

. Median =

\$2.40

. Total system operating cost =

\$340.3\text{ million}

; total trips =

154.5\text{ million}

. Weighted average =

\$340.3 / 154.5 \approx \$2.2026

. Median (

\$2.40

) > Weighted Average (

\$2.2026

). Statement 1 is True.

Evaluates median vs. weighted average accurately across unequal trip volumes.

2

Filter and calculate subset fleet means for Statement 2.

Corridors with Zero-Emission

120

), C-South (

200

), C-Central (

.

165 > 113.33

, so the statement claiming

165 < 113.33

is False.

Compares conditional subgroup averages correctly.

3

Apply conditional filtering for Statement 3 based on On-Time Departure Rate.

Corridors with On-Time Departure Rate

\ge 88\%

include C-North, C-East, C-West, C-Harbor, and C-Airport. C-South has an On-Time Departure Rate of

85\% < 88\%

The table below presents operational and usage metrics for eight branch locations within a regional public library network during 2025:

Branch Code	Total Volumes (thousands)	Active Cardholders (thousands)	Annual Circulations (thousands)	Operating Expenses ($ thousands)	Digital Resource Accesses (thousands)
CEN	450	60	900	3,600	300
NOR	120	25	300	1,000	150
EAS	80	16	160	640	80

HAR	110	22	220	880	110
UPL	160	32	480	1,440	160

Consider the following three statements regarding the data:

I. The median number of Annual Circulations among the branches with more than 20,000 Active Cardholders is greater than 350,000.
II. For Eastgate (EAS), the ratio of Annual Circulations per Total Volume is higher than that for West End (WES).
III. Exactly three branches satisfy both of the following conditions: Operating Expenses per Circulation are strictly less than $4.00, AND Digital Resource Accesses exceed 140,000.

Which of the following correctly identifies the truth values (True or False) of Statements I, II, and III, respectively?

Statement I: True; Statement II: True; Statement III: True

Statement I: False; Statement II: True; Statement III: True

Statement I: True; Statement II: False; Statement III: True

Statement I: True; Statement II: True; Statement III: False

Statement I: False; Statement II: False; Statement III: True

Cevabı ve açıklamayı göster

Cevap: Statement I: True; Statement II: True; Statement III: True

Cevap

Statement I: True; Statement II: True; Statement III: True

The correct option is the one identifying all three statements as True. Statement I is True because the median circulation of the 5 filtered branches is 480,000, which exceeds 350,000. Statement II is True because EAS has a circulation-to-volume ratio of 2.0 compared to 1.6 for WES. Statement III is True because NOR, SOU, and UPL are the exactly three branches that satisfy both expenses per circulation < $4.00 and digital accesses > 140,000.

Adım Adım Çözüm

1

Evaluate Statement I by filtering and sorting.

Branches with Active Cardholders > 20 (in thousands) are CEN (60), NOR (25), SOU (40), HAR (22), and UPL (32), total 5 branches. Their Annual Circulations (in thousands) are 900, 300, 500, 220, and 480. Sorting these values yields 220, 300, 480, 500, 900. The median (3rd value) is 480 thousand (480,000). Since 480,000 > 350,000, Statement I is True.

Filtering required strict application of the cardholder threshold before ordering the circulation data.

2

Evaluate Statement II by calculating row ratios.

For EAS, Circulations / Volumes = 160 / 80 = 2.0. For WES, Circulations / Volumes = 240 / 150 = 1.6. Since 2.0 > 1.6, Statement II is True.

Ratio comparison requires placing Circulations in the numerator and Volumes in the denominator.

3

Evaluate Statement III using dual-condition logical filtering.

Calculate Operating Expenses (

thousands) / Annual Circulations (thousands) to get

per circulation: CEN (3,600 / 900 =

4.00), NOR (1,000 / 300 =

3.33), EAS (640 / 160 =

4.00), WES (960 / 240 =

4.00), SOU (1,500 / 500 =

3.00), RIV (720 / 225 =

3.20), HAR (880 / 220 =

4.00), UPL (1,440 / 480 =

3.00). Branches with expense per circulation strictly less than $4.00 are NOR, SOU, RIV, and UPL. Among these, Digital Resource Accesses (> 140 thousand) are NOR (150), SOU (250), and UPL (160). RIV has only 90. Exactly 3 branches meet both conditions. Statement III is True.

Strict inequality rules out branches with expenses per circulation equal to $4.00.

Cevap: False

Cevap

False. Only Statement II is True (Statement I and Statement III are both False). Therefore, exactly one statement is True, making the overall claim False.

Evaluating each component statement reveals that Statement I is False (median is

17.25

hours, which is not less than

17.0

), Statement II is True (all four terminals with

\ge 75\%

crane automation exceed

87\%

clearance rate), and Statement III is False (mean cargo volume is

1,288.75

, not greater than

1,350

). Because only one statement is True, the claim stating that exactly two statements are True is False.

Top 4 terminals by volume: Terminal C (

2,100

1,600

), and Terminal A (

1,250

). Their Average Berth Dwell Times are

14.2

16.0

,

21.5

, and

18.5

hours, respectively. Ordered ascending, these values are

14.2, 16.0, 18.5, 21.5

. The median is the average of the two middle values:

\frac{16.0 + 18.5}{2} = 17.25

hours. Since

17.25 > 17.0

, Statement I is False.

Correctly identifying the median of an even set requires ordering the values and taking the midpoint of the two central numbers.

2

Evaluate Statement II by checking the On-Time Vessel Clearance Rate for terminals with an Automated Crane Ratio

\ge 75\%

.

Terminals with Automated Crane Ratio

\ge 75\%

Cevap: True

Cevap

The statement is True because Statements I and III evaluate to True, while Statement II evaluates to False, making exactly two statements True.

The overarching statement is correct because evaluating each of the three sub-statements shows that Statement I is True (median is \$6,350/ton), Statement II is False (VF-104 has the highest energy per ton but not the highest operating cost), and Statement III is True (mean energy is 445 MWh). Therefore, exactly two statements are True.

Adım Adım Çözüm

1

Filter facilities with Water Recycled

\ge 90\%

and calculate their Revenue per metric ton of Crop Yield.

Matching facilities: VF-101 (

92\%

), VF-103 (

95\%

), VF-105 (

90\%

), VF-107 (

94\%

).
Revenue per metric ton calculations:
- VF-101:

\frac{\$720,000}{120} = \$6,000/\text{ton}

- VF-103:

\frac{\$975,000}{150} = \$6,500/\text{ton}

- VF-105:

\frac{\$682,000}{110} = \$6,200/\text{ton}

- VF-107:

\frac{\$858,000}{130} = \$6,600/\text{ton}

Statement I requires computing revenue yield efficiency for a subset of rows filtered by water recycling rate.

2

Find the median of the filtered revenue per metric ton values to test Statement I.

Ordered set:

\{\$6,000, \$6,200, \$6,500, \$6,600\}

. Median =

\frac{\$6,200 + \$6,500}{2} = \$6,350

. Since

\$6,350 > \$6,000

, Statement I is TRUE.

The median of an even-numbered dataset is the arithmetic mean of the two middle values.

3

Calculate Energy Consumption per metric ton of Crop Yield for all facilities to identify the maximum, then compare with Operating Cost per kg to test Statement II.

Energy per metric ton rates:
- VF-101:

\frac{480}{120} = 4.0\text{ MWh/ton}

- VF-102:

\frac{315}{85} \approx 3.71\text{ MWh/ton}

- VF-103:

\frac{600}{150} = 4.0\text{ MWh/ton}

- VF-104:

\frac{418}{95} = 4.4\text{ MWh/ton}

(Highest)
- VF-105:

\frac{462}{110} = 4.2\text{ MWh/ton}

- VF-106:

\frac{294}{70} = 4.2\text{ MWh/ton}

- VF-107:

\frac{546}{130} = 4.2\text{ MWh/ton}

VF-104 has the highest Energy per metric ton (

4.4

). Its Operating Cost is \$4.80/kg. However, VF-106 has the highest Operating Cost at \$5.60/kg. Thus, Statement II is FALSE.

Testing Statement II requires identifying the maximum value of a calculated row-level ratio and checking if it coincides with the column maximum of another metric.

4

Calculate the mean Energy Consumption across all seven facilities to test Statement III.

Sum of Energy Consumption =

480 + 315 + 600 + 418 + 462 + 294 + 546 = 3,115\text{ MWh}

. Mean =

\frac{3,115}{7} = 445\text{ MWh}

. Since

445 < 450

, Statement III is TRUE.

Determining the truth value of Statement III requires computing an aggregate mean across the entire dataset.

5

Synthesize the boolean evaluations of the three statements to determine the final truth value.

Statement I: True, Statement II: False, Statement III: True. Exactly two of the three statements are True, which confirms that the overarching statement is True.

The main question stem asserts that exactly two statements are True.

Cevap

Statement I matches with the evaluation of True (median rate is 86%). Statement II matches with the evaluation of False (R-105 has 80 flights while minimum is 45). Statement III matches with the evaluation of False (the ratio increases from R-102 to R-105).

Each statement is evaluated against the quantitative data provided in the table. Statement I correctly identifies the four routes exceeding 800 miles and calculates their median as 86%. Statement II correctly identifies that R-105 has the highest load factor (90%) but 80 flights, whereas R-106 has the minimum flights (45). Statement III correctly identifies a counterexample where the fuel-to-distance ratio increases from R-102 to R-105.

1

Filter and compute the median for Statement I.

Qualifying routes (>800 miles): R-102 (75%), R-105 (80%), R-103 (92%), R-106 (94%). Sorted rates: [75%, 80%, 92%, 94%]. Median = $\frac{80\% + 92\%}{2} = 86\%$ > 85%.

Identify sub-population based on distance criterion and determine the median of an even-sized dataset.

2

Locate maximum load factor and compare scheduled flights for Statement II.

Max load factor = 90% (R-105, 80 flights). Fewest flights overall = 45 flights (R-106). Since 80 != 45, statement is False.

Identify row-level extrema across two independent columns (Load Factor and Flights Scheduled).

3

Calculate rates/ratios for Statement III across increasing distances.

R-102 (820 miles): $\frac{2300}{820} \approx 2.805$ gal/mi. R-105 (960 miles): $\frac{2850}{960} = 2.96875$ gal/mi. Ratio increases, so trend is not strictly decreasing.

Cevap: True

Cevap

True. Statements 1 and 2 are True, while Statement 3 is False, meaning exactly two of the three statements are True.

Evaluating the individual statements reveals that Statement 1 is True (the median of {40, 60, 75, 95} is 67.5), Statement 2 is True (operating costs for Cellulosic and Algae facilities are

0.72,

1.10,

0.68, and

0.98, all greater than

0.65), and Statement 3 is False (PureBio's total cost of

60.8 Million exceeds GreenFuel X's total cost of $44.0 Million). Since exactly two statements are True, the overall compound assertion is True.

Adım Adım Çözüm

1

Evaluate Statement 1: Identify facilities with Carbon Intensity Reduction ≥ 70% and calculate their median Annual Output.

Facilities satisfying the condition are GreenFuel X (82%), PureBio (74%), Vanguard Bio (85%), and NextGen Fuel (70%). Their outputs are 40, 95, 60, and 75 Million Liters, respectively. Ordering these values: 40, 60, 75, 95. The median of an even set of four numbers is

(60 + 75) / 2 = 67.5

Million Liters. Thus, Statement 1 is True.

Correctly filtering by the conditional threshold (70%) and sorting the output values is required to calculate the median of an even dataset.

2

Evaluate Statement 2: Filter for facilities using Cellulosic or Algae feedstock and compare their Operating Costs to $0.65.

Facilities matching Cellulosic or Algae feedstock are BioAlpha (

0.72), GreenFuel X (

1.10), TerraFuel (

0.68), and Vanguard Bio (

0.98). Every single one of these operating costs is strictly greater than $0.65. Thus, Statement 2 is True.

A universal condition ('for all') requires checking every matching row to ensure no counterexample exists.

3

Evaluate Statement 3: Identify facilities with the highest and lowest Capacity Utilization Rates, compute their total annual operating costs, and compare.

Highest Capacity Utilization Rate: PureBio (95%). Total annual operating cost =

95 \text{ Million L} \times \$0.64/\text{L} = \$60.8 \text{ Million}

. Lowest Capacity Utilization Rate: GreenFuel X (75%). Total annual operating cost =

40 \text{ Million L} \times \$1.10/\text{L} = \$44.0 \text{ Million}

. Since

\$60.8 \text{ Million} > \$44.0 \text{ Million}

, the highest utilization facility did NOT incur a lower cost. Thus, Statement 3 is False.

Row-level product calculations must be performed accurately for both extreme values before evaluating the inequality.

4

Synthesize the truth values of the three statements to evaluate the overall assertion.

Statement 1 = True, Statement 2 = True, Statement 3 = False. Total number of True statements = 2. Therefore, the assertion 'Exactly two of the three statements below are True' is True.

The top-level boolean logic requires assessing whether the count of True individual statements equals 2.

Adım Adım Çözüm

1

Evaluate Statement I by determining the median staff count and mean operating cost.

Sorted staff counts: 18, 22, 28, 31 (Laurel Heights), 35, 42, 50. Median plant is Laurel Heights with an operating cost of

310. Mean operating cost = (320 + 280 + 410 + 250 + 340 + 450 + 310) / 7 = 2360 / 7 ≈

337.14. Since

310 is less than

337.14, Statement I is False.

Identify the median position (4th out of 7) and compare its specific column value to the unweighted mean across all rows.

2

Evaluate Statement II by filtering plants with compliance > 98.5% and calculating aggregate capacity to staff ratio.

Qualifying plants are Blue River, Pine Creek, Cedar Ridge, and Laurel Heights. Total capacity = 80 + 110 + 60 + 70 = 320 MGD. Total staff = 42 + 50 + 35 + 31 = 158. Ratio = 320 / 158 ≈ 2.025 MGD/staff. Since 2.025 > 2.0, Statement II is True.

Filter rows according to a conditional threshold, aggregate columns across the selected subset, and perform ratio division.

Evaluate Statement III by sorting by Energy Consumption and comparing capacities of the 3rd-lowest energy plant and 1st-lowest cost plant.

Energy ordered plants: Pine Creek (1,150), Blue River (1,200), Laurel Heights (1,300). 3rd-lowest is Laurel Heights (Capacity = 70 MGD). Lowest operating cost plant is Pine Creek ($250, Capacity = 110 MGD). Comparing capacities: 70 MGD < 110 MGD. Statement III is False.

Cevap: Exactly Statements I and II are true

Cevap

Statements I and II are True, while Statement III is False.

Evaluating each statement systematically shows that Statement I is True because the sorted costs for eligible fleets are

14.10,

15.80,

16.50,

18.20, giving a median of

15.80 (which exceeds

15.00). Statement II is True because Gamma-3 meets the delivery rate threshold (> 92.0%) and holds both the minimum flight hours (310) and minimum operating cost (

10.50) among those fleets. Statement III is False because the filtered fleets (Alpha-1, Gamma-3, Zeta-6) have a mean flight hour of 373.33 hours, which is less than 400 hours. Thus, exactly Statements I and II are true.

Adım Adım Çözüm

1

Evaluate Statement I by filtering and sorting Operating Cost per Km for fleets with Payload Capacity

\ge 150\text{ kg}

.

Fleets meeting the condition are Alpha-1 (150 kg), Beta-2 (200 kg), Delta-4 (250 kg), Epsilon-5 (180 kg), and Eta-7 (220 kg). Their operating costs sorted from lowest to highest are

12.40,

14.10,

15.80,

16.50,

18.20. The median of these 5 values is the 3rd value, which is

15.80. Since

15.80 >

15.00, Statement I is TRUE.

Finding the median of an odd number of items requires ordering the subset values and taking the middle element.

2

Evaluate Statement II by filtering fleets with On-Time Delivery Rate

> 92.0\%

.

Fleets meeting the condition are Alpha-1 (94.5%), Gamma-3 (96.0%), Epsilon-5 (93.0%), and Zeta-6 (97.5%). Among these 4 fleets, Gamma-3 has the lowest Total Flight Hours (310 hours) and also the lowest Operating Cost per Km ($10.50). Therefore, Statement II is TRUE.

Cross-column multi-condition filtering verifies both the minimum flight hours and minimum operating cost within the subset.

3

Evaluate Statement III by calculating the mean Total Flight Hours for fleets with Payload Capacity

< 180\text{ kg}

.

Fleets with Payload Capacity strictly less than 180 kg are Gamma-3 (120 kg), Zeta-6 (140 kg), and Alpha-1 (150 kg). (Epsilon-5 is excluded as its payload is exactly 180 kg). Their flight hours are 310, 390, and 420. Mean =

\frac{310 + 390 + 420}{3} = \frac{1120}{3} \approx 373.33\text{ hours}

. Since

373.33 < 400

, Statement III is FALSE.

Computing the arithmetic mean of the correctly filtered subset shows it is below the threshold of 400 hours.
