An elevator has a placard stating that the maximum capacity is 1384 lb-8 passengers. So, 8 adult male passengers can have a mean weight of up to 1384/8=173 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 173 Ib.

The probability the elevator is overloaded is (Round to four decimal places as needed.) Does this elevator appear to be safe? D O A. No, 8 randomly selected people will never be under the weight limit. OB. No, there is a good chance that 8 randomly selected adult male passengers will exceed the elevator capacity. OC. Yes, 8 randomly selected adult male passengers will always be under the weight limit. OD. Yes, there is a good chance that 8 randomly selected people will not exceed the elevator capacity.

An elevator has a placard stating that the maximum capacity is 1384 lb-8 passengers. So, 8 adult male
passengers can have a mean weight of up to 1384/8 = 173 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 173
Ib. (Assume that weights of males are normally distributed with a mean of 180 lb and a standard deviation of
29 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, 8 randomly selected people will never be under the weight limit.
OB. No, there is a good chance that 8 randomly selected adult male passengers will exceed the elevator
capacity.
OC. Yes, 8 randomly selected adult male passengers will always be under the weight limit.
O D. Yes, there is a good chance that 8 randomly selected people will not exceed the elevator capacity.
