An elevator has a placard stating that the maximum capacity is 2415 Ib-15 passengers so, 15 adult male passengers can have a mean weight of up to 2415/=161 pounds. if the elevator is loaded with 15 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 161 lb. (Assume that weights of males are normally distributed with a mean of 171 lb and a standard deviation of 28 lb.) Does this elevator appear to be safe?​
