answered
To find the mean, we need to sum up all the hours spent on math homework and divide by the number of students.
Looking at the graph, we can approximate the values of each bar and calculate the sum:
(1 x 5) + (2 x 7) + (3 x 4) + (4 x 3) + (5 x 1) = 5 + 14 + 12 + 12 + 5 = 48
There are a total of 20 students represented in the graph.
Mean = Total hours / Number of students
Mean = 48 / 20
Mean = 2.4 hours
Therefore, the mean number of hours students spent on math homework is 2.4 hours.
