To find the mean, we need to first find the sum of all the values and then divide it by the total number of values.
From the graph, we can see that there are:
- 2 students who spent 1 hour on math homework
- 4 students who spent 3 hours on math homework
- 3 students who spent 5 hours on math homework
- 1 student who spent 6 hours on math homework
Adding these values together:
(2 x 1) + (4 x 3) + (3 x 5) + (1 x 6) = 2 + 12 + 15 + 6 = 35
Now, we divide this sum by the total number of students:
2 + 4 + 3 + 1 = 10
35 / 10 = 3.5
Therefore, the mean number of hours students spent on math homework is 3.5 hours.
