To find the mean, we need to calculate the total number of hours spent on math homework and then divide it by the number of students in the sample.
From the graph, we can see that there are 5 students who spent 1 hour on math homework, 3 students who spent 2 hours, 1 student who spent 3 hours, and 1 student who spent 4 hours.
Total hours = (5*1) + (3*2) + (1*3) + (1*4) = 5 + 6 + 3 + 4 = 18 hours
Total number of students = 5 + 3 + 1 + 1 = 10 students
Mean number of hours spent on math homework = Total hours / Total number of students = 18 hours / 10 students = 1.8 hours
Therefore, the mean number of hours students spent on math homework is 1.8 hours.
The graph shows the number of hours randomly selected students spent on math homework. What is
