Question
An elevator has a placard stating that the maximum capacity is 1896 lb—12 passengers. So, 12 adult male passengers can have a mean weight of up to 1896 / 12 = 158 pounds. If the elevator is loaded with 12 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 158 lb. (Assume that weights of males are normally distributed with a mean of 166 lb and a standard deviation of 33 lb.) Does the elevator appear to be safe?

The probability the elevator is overloaded is [ ].  
(Round to four decimal places as needed.)
