Answer

The median number of hours worked per day for this week is 7.
The median of a set of data is the middle value when the numbers are arranged in order. Sorting the given hours worked from least to greatest gives: 2, 3, 5, 7, 7, 8, 10. Since there are 7 data points, the middle value is the 4th value, which is 7.

Step-by-Step Solution

1
Arrange the daily hours worked in ascending order.
The sorted list of hours is: 2, 3, 5, 7, 7, 8, 10.
Finding the median of a data set requires organizing the values from least to greatest.
2
Identify the middle value in the ordered list of 7 values.
The 4th value in the sorted list is 7.
Since the data set has an odd number of values (7), the median is the single middle value, located at the 4th position.
