An elevator has a placard stating that the maximum capacity is 1540 lb-10 passengers. So, 10 adult male passengers can have a mean weight of up to 1540 /10 = 154 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 154 Ib. (Assume that weights of males are normally distributed with a mean of 161 Ib and a standard deviation of 32 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, 10 randomly selected adult male passengers will always be under the weight limit. O B. Yes, there is a good chance that 10 randomly selected people will not exceed the elevator capacity. OC. No, there is a good chance that 10 randomly selected adult male passengers will exceed the elevator capacity. O D. No, 10 randomly selected people will never be under the weight limit.
