Question
An elevator has a placard stating that the maximum capacity is 1884 lb-12 passengers. So, 12 adult male passengers can have a mean weight of up to 1884 /12 = 157 pounds. If the elevator is loaded with 12 adult male passengers, find the
probability that it is overloaded because they have a mean weight greater than 157 lb. (Assume that weights of males are normally distributed with a mean of 163 Ib and a standard deviation of 29 lb.) Does this elevator appear to be safe?
The probability the elevator is overloaded is

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 12 randomly selected people will exceed the elevator capacity.
O B. Yes, there is a good chance that 12 randomly selected people will not exceed the elevator capacity.
OC. Yes, 12 randomly selected people will always be under the weight limit.
O D. No, 12 randomly selected people will never be under the weight limit.
