The daily agricultural output (in tonnes) of a cassava farm over five consecutive days was recorded as 12, 15, 18, 15, and 20. What is the mean daily output of the farm in tonnes?

Answer: 16 tonnes

Answer

The mean daily output of the farm is 16 tonnes.

The arithmetic mean is computed by adding all data values together (

12 + 15 + 18 + 15 + 20 = 80

) and dividing by the total number of data points (

5

), which gives

80 \div 5 = 16

tonnes.

Step-by-Step Solution

Calculate the total output by summing all daily figures.

12 + 15 + 18 + 15 + 20 = 80 tonnes

Finding the arithmetic mean requires calculating the aggregate total of all observations.

Divide the total output by the number of observations (days).

80 / 5 = 16 tonnes

The formula for the arithmetic mean of a sample is the sum of all values divided by the total number of values.
