Answer:

Part A: 20 students

Part B: 4 hours

Step-by-step explanation:

Part A:

To find the number of students surveyed, we count the number of x there are in the graph.

students = 1 + 2 + 3 + 5 + 1 + 1 + 3 + 2 + 2 = 20

Part B:

To find the mean, we need to find the total number of hours volunteered first.

hours = 1x0 + 2x1 + 3x3 + 5x3 + 1x4 + 1x5 + 3x6 + 2x7 + 2x8 = 80

Now, we can find the mean. We divide the total number of hours volunteered by the number of students.

Mean = 80 ÷ 20 = 4
