An elevator has a placard stating that the maximum capacity is 3700 lb-26 passengers. So, 26 adult male passengers can have a mean weight of up to 3700/26 = 142 pounds. Assume that weights of males are normally distributed with a mean of 175 lb anda standard deviation of 36 lb. a. Find the probability that 1 randomly selected adult male has a weight greater than 142 lb. b. Find the probability that a sample of 26 randomly selected adult males has a mean weight greater than 142 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 142 lb is (Round to four decimal places as needed.) ...
