An elevator has a placard stating that the maximum capacity is 3600lb —25 passengers. So, 25 adult male passengers can have a mean weight of up to 3600 divided by 25 equals 144 pounds.3600/25=144 pounds. Assume that weights of males are normally distributed with a mean of 184lb and a standard deviation of 25lb. a. Find the probability that 1 randomly selected adult male has a weight greater than 144lb. b. Find the probability that a sample of 25 randomly selected adult males has a mean weight greater than 144 lb. c. What do you conclude about the safety of this elevator?
