Assume men's weights are normally distributed with a mean of 172 lb and an s.d. of 29lb.
If one selected find P his weight is between 163 and 176lb.
Part B is my problem-using the central limit theorem, if 16 men are randomly selected, find the P they have a mean weight between 166lb and 176 lb. The answer is not .5118 but .5055.© BrainMass Inc. brainmass.com November 30, 2021, 12:11 am ad1c9bdddf
