An elevator has a placard stating that the maximum capacity is 1660 lblong dash10 passengers. So, 10 adult male passengers can have a mean weight of up to 1660 divided by 10 equals 166 pounds. If the elevator is loaded with 10 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 166 lb. (Assume that weights of males are normally distributed with a mean of 169 lb and a standard deviation of 30 lb.) Does this elevator appear to be safe?
