Question: Men have hips normally dist. with a mean of 14.4 in. & s.d. of 1.0. Assume 2 male riders randomly selected. Find the probability that their mean hip width is greater than 15.5 in. Please show steps to arrive at the solution
Also: Is the design appropriate assuming that the 2 men have a mean breadth of 16.75 inches?
This solution finds the probability of an event related to a sample mean by applying the central limit theorem.
