An elevator has a placard stating that the maximum capacity is 2580 lb-15 passengers. So, 15 adult male passengers can have a mean weight of up to 2580 / 15 = 172 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 172 lb. (Assume that weights of males are normally distributed with a mean of 176 lb and a standard deviation of 33 lb. ) Does this elevator appear to be safe? The probability the elevator is overloaded is (Round to four decimal places as needed.) Does this elevator appear to be safe? O A. Yes, 15 randomly selected adult male passengers will always be under the weight limit. O B. Yes, there is a good chance that 15 randomly selected people will not exceed the elevator capacity. O C. No, 15 randomly selected people will never be under the weight limit. O D. No, there is a good chance that 15 randomly selected adult male passengers will exceed the elevator capacity 4
