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.
To find the mean number of hours students spent on math homework, we need to add up all the hours and then divide by the number of students.
From the graph, we can see that the number of students who spent:
- 1 hour: 5 students
- 2 hours: 7 students
- 3 hours: 10 students
- 4 hours: 6 students
- 5 hours: 4 students
- 6 hours: 3 students
- 7 hours: 5 students
To find the mean:
(1*5 + 2*7 + 3*10 + 4*6 + 5*4 + 6*3 + 7*5) / (5 + 7 + 10 + 6 + 4 + 3 + 5)
= (5 + 14 + 30 + 24 + 20 + 18 + 35) / 40
= 146 / 40
= 3.65
Therefore, the mean number of hours students spent on math homework is approximately 3.65 hours.
