An elevator has a placard stating that the maximum capacity is 2610 lb—15 passengers. So, 15 adult male passengers can have a mean weight of up to 2610/15=174 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 174 lb. (Assume that weights of males are normally distributed with a mean of 177 lb and a standard deviation of 26 lb .) Does this elevator appear to be safe? 1. The probability the elevator is overloaded is____ 2. Does the elevator appear safe? (choose the best answer below) A - No, 15 randomly selected people will never be under wright B - Yes, 15 randomly selected adult male passengers will always be under the weight limit. C - No, there is a good chance that 15 randomly selected adult male passengers will exceed the elevator capacity. D - Yes, there is a good chance that 15 randomly selected people will not exceed the elevator capacity.
