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 that weights of males are normally distributed with a mean of 184 lb and a standard deviation of 36 lb. 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 a mean weight greater than 154 lb. c. What do you conclude about the safety of this elevator? a. The probability that 1 randomly selected adult male has a weight greater than 154 lb is (Round to four decimal places as needed.)
