An elevator has a placard stating that the maximum capacity is 1860 lb-12 passengers. So, 12 adult male passengers can have a mean weight of up to 1860/12= 155 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 155 lb. (Assume that weights of males are normally distributed with a mean of 161 lb and a standard deviation of 25 lb.) Does this elevator appear to be safe? The probability the elevator is overloaded is (Round to four decimal places as needed.)
