1280 lb—8 passengers. So, 8 adult male passengers can have a mean weight of up to 1280/8=160 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 160 lb. (Assume that weights of males are normally distributed with a mean of 167 lb and a standard deviation of 34 lb.) Does this elevator appear to be safe?
