Question

The dot plots represent the number of students who enrolled each year for the AP psychology course at two schools. The data represents the last 24 years. Which statement is true based on the mean number of students enrolled in the course?

Answer 1

the correct answer is D

Explanation:

Answer 2

D

The mean for school 1 is 466/24=19.42 (rounded)

The mean for school 2 is 537/24=22.375

It doesn't ask for the mean absolute deviation, otherwise it would be the reverse of d (which is c).
