A statistics class of 25 students took a test out of 100 points, and the class average was a 79 with a standard deviation of 8 points. a) How many standards deviations from the mean is a student who scored a 91?
b) How many standards deviations from the mean is a student who scored a 72?
c) If a student scores a 72, what percent of the class scored better on the test? (Round to the nearest tenth of a percent)
d) What percent of students scored in between a 72 and 91 on the test (Round to the nearest tenth of a percent)
