An elevator has a placard stating that the maximum capacity is 2445 lb-15 passengers. So, 15 adult male passengers can have a mean weight of up to 2445 / 15 = 163 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 163 lb. (Assume that weights of males are normally distributed with a mean of 169 lb and a standard deviation of 26 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. No, 15 randomly selected people will never be under the weight limit. O B. No, there is a good chance that 15 randomly selected adult male passengers will exceed the elevator capacity. O C. Yes, 15 randomly selected adult male passengers will always be under the weight limit. O D. Yes, there is a good chance that 15 randomly selected people will not exceed the elevator capacity
