The elevator in a car rental building has a placard stating that the maximum capacity "4000 lb or 27 passengers." Because 4000/27 = 148, this converts to a mean passenger weight of 148 lb when the elevator is full. We will assume a worst-case scenario in which the elevator is filled with 27 adult males. Based on Data Set 1 "Body Data" in Appendix B, assume that adult males have weights that are normally distributed with a mean of 189 lb and a standard deviation of 39 lb. a.) Find the probability that 1 randomly selected adult male has a weight greater than 148 lb. b.) Find the probability that a sample of 27 randomly selected adult males has a mean weight greater than 148 lb.
