Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the mean number of hours students spent on math homework, we need to sum up all the hours and then divide by the total number of students.

Based on the graph, the total number of hours students spent on math homework is:

1 + 2 + 2 + 3 + 4 + 5 + 6 + 7 + 9 = 39

The total number of students is 9.

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

39 hours / 9 students = 4.33 hours

Rounded to two decimal places, the mean number of hours students spent on math homework is 4.33 hours.

Therefore, the closest option is:

b. 2.14 hours
