Suppose that the mean value of interpupillary distance for all adult males is 65 mm, and the population standard deviation is 5 mm.
a) find the probability that a male selected at random will have an interpupillary distance less that 67.5 mm. assume that the distribution of interpupillary distances is approximately normal.
b) if a sample of 22 adult males is selected, what is the probability that the sample average distance x is between 64.3 and 66.4 mm?
c) given that the sample size in part (b) is small, explain why we could still use the z-table to answer the question.
