An elevator has a placard stating that the maximum capacity is 1296 lb-8 passengers. So, 8 adult male passengers can have a mean weight of up to 1296/8= 162 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 162 lb. (Assume that weights of males are normally distributed with a mean of 172 lb 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. No, there is a good chance that 8 randomly selected adult male passengers will exceed the elevator capacity. O B. Yes, there is a good chance that 8 randomly selected people will not exceed the elevator capacity. O C. Yes, 8 randomly selected adult male passengers will always be under the weight limit. O D. No, 8 randomly selected people will never be under the weight limit.
