Question

A certain college randomly selected 30 freshman students who completed college algebra during their first semester. Fifteen students were chosen from students who took the course at night and 15 students were chosen from students who took the course during the day. The following statistical information was calculated from their final grades.
Day Night
Mean 76 68
Median 68 72
Mode 64 72
Range 38 53

Based on these samples, what generalization can be made? (Assume that a score of 70 or greater is a passing score.)
A.
The mean score for the night students was higher than the mean score for the day students.

B.
The median score for the day students was higher than the median score for the night students.

C.
The mean score for the day students was higher than the mean score for the night students.

D.
The range of scores was larger for the day students than for the night students.

Answer 1

It's C because if you look at the day and night students, the mean score for the day students was actually higher then the mean score for the night student.
