Question 1075236: At one university, the students are given z-scores at the end of the semester rather than the traditional GPA's. A student who received a Z score of 2.0 actually had a GPA score of 3.7. Given the standard deviation of all GPA's was 0.5, what was the mean GPA?

z score of 2 means (x-mean)/sd=2
(3.7-mean)=2*sd=1
so 3.7-mean=1
The mean is GPA score of 2.7
