An elevator has a placard stating that the maximum capacity is 1328 Ib-8 passengers. So, 8 adult male passengers can have a mean weight of up to 1328/8 166 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 166 lb. (Assume that weights of males are normally distributed with a mean of 173 lb and a standard deviation of 26 lb.) Does this elevator appear to be safe? The probability the elevator is overloaded is (Round to four decimal places as needed.)
