An elevator has a placard stating that the maximum capacity is 4300 lb-28 passengers. So, 28 adult male passengers can have a mean weight of up to 4300/28 = 154 pounds. Assume weights of males are normally distributed with a mean of 178 Ib and a standard deviation of 34 Ib. a. Find the probability that 1 randomly selected adult male has a weight greater than 154 lb. b. Find the probability that a sample of 28 randomly selected adult males has c. What do you conclude about the safety of this elevator? mean weight greater than 154 lb.
