Question

A class of 27 students had a mean of 83 on a math quiz. The 12 girls in the class had a mean of 80.5 on the quiz. What was the mean of the boys’ scores?

a. 77
b. 77.5
c. 85
d. 85.5

Answer 1

D

Explanation:

It would most likely have to be above 83 to bring the average down, so A and B are out. It would most likely be D, since it would equally be 5 between 80.5 and 85.5 to get an even 83.
