Question

Use the image to answer the question.

A bar graph shows the number of hours spent on math homework versus the number of students. The horizontal axis shows the time in hours ranging from 1 to 5 in increments of 1. The vertical axis shows the number of students ranging from 0 to 10 in increments of 1. The data with time in hours, followed by the number of students is as follows: 1 to 8, 2 to 6, 3 to 4, 4 to 2, and 5 to 1.

The graph shows the number of hours randomly selected students spent on math homework. What is the mean number of hours students spent on math homework?

The mean number of hours spent on math homework can be calculated by adding up the total number of hours (1+1+2+2+2+2+2+2+3+3+3+3+4+4+5) and then dividing by the total number of students (8+6+4+2+1 = 21).

Total number of hours = 35
Total number of students = 21
Mean = Total number of hours / Total number of students = 35 / 21 ≈ 1.67 hours

Therefore, the mean number of hours students spent on math homework is 1.67 hours.
