A college student takes a standardized test and scores a 163

A college student takes a standardized test and scores a 163. If the mean is 155 and the standard deviation is 7, what is the student

x = 163

u = mean = 155

SD = 7

z = (x - u) / SD

z = (163 -155) / 7

z = 8/7 = 1.14

0.87286 is the value from the z-score table

So, the student is in the 87th percentile approximately
