Recall that weight in adult women is normally distributed with = 140 pounds and = 15 pounds. Suppose a sample of size n = 16 is taken and their average weight X computed.
(a) What is the standard error of the sampling distribution?
(b) What is the probability that the sample mean X is between 135 and 145?
(c) What is the probability that the sample mean X is less than 142?
