The height of males is normally distributed with a mean of 69 inches and a standard deviation of 2.5 inches. What is the probability that the height of a randomly selected male is between 66 and 71 inches?
stat/ probability -
Z = (score-mean)/SD
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion related to the Z scores.
