An elevator has a placard stating that the maximum capacity is 1368 Ib-B passengers. So, 8 adult male passengers can have a mean weight of up to 1368 /8 =171 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 171 lb. (Assume that weights of males are normally distributed with a mean of 176 lb and a standard deviation of 27 lb.) Does this elevator appear to be safe? The probability the elevator is overloaded is (Round to four decimal places as nooded.)

1368 /8 =171 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
171 lb. (Assume that weights of males are normally distributed with a mean of 176 lb and a standard deviation of 27 lb.) Does this elevator appear to be safe?
The probability the elevator is overloaded is
(Round to four decimal places as nooded.)
