An elevator has a placard stating that the maximum capacity is 1296 lb long dash — 8 passengers. So, 8 adult male passengers can have a mean weight of up to 1296 divided by 8 equals 162 pounds. 1296/8=162 pounds. If the elevator is loaded with 8 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 162 lb. (Assume that weights of males are normally distributed with a mean of 170 lb and a standard deviation of 29 lb.) Does this elevator appear to be safe?
