A. An elevator’s maximum capacity is 16 passengers or a total weight of 2500 lb. Male weights are normally distributed with a mean of 189 lb. and a standard deviation of 39 lb. Find the probability that 1 randomly selected male has a weight greater than 156.25 lb. (Round to four decimal places.)

B.An elevator’s maximum capacity is 16 passengers or a total weight of 2500 lb. Male weights are normally distributed with a mean of 189 lb. and a standard deviation of 39 lb. Find the probability that a sample of 16 males have a mean weight greater than 156.25 lb. (which exceeds the maximum capacity). (Round to four decimal places.)
