An elevator has a placard stating that the maximum capacity is 1240 lb8 passengers. So, 8 adult male passengers can have a mean weight of up to 1240/ 8 = 155 pounds. If the elevator is loaded with 8 adult male passengers, nd 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 165 lb and a standard deviation of 29 lb.) Does this elevator appear to be safe
