Assume that the population of weights of men is normally distributed with mean 172 lb and standard deviation 29 lb.

a. If an individual man is randomly selected, find the probability that his weight will be greater than 175 lb. (Round to four decimal places as needed.)

b. Find the probability that 20 randomly selected men will have a mean weight that is greater than 175 lb. (Round to four decimal places as needed.)

Please show all work as if inputting into a graphing calculator.
