An elevator has a placard stating that the maximum capacity is 2280 lb—15 passengers. So, 15 adult male passengers can have a mean weight of up to 2280/15=152 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 152 lb. (Assume that weights of males are normally distributed with a mean of 161 lb and a standard deviation of 25 lb.) Does this elevator appear to be safe? The probability the elevator is overloaded is nothing. (Round to four decimal places as needed.) Does this elevator appear to be safe? A. No, there is a good chance that 15 randomly selected people will exceed the elevator capacity. B. Yes, there is a good chance that 15 randomly selected people will not exceed the elevator capacity. C. No, 15 randomly selected people will never be under the weight limit. D. Yes, 15 randomly selected people will always be under the weight limit.

An elevator has a placard stating that the maximum capacity is
probability that it is overloaded because they have a mean weight greater than
normally distributed with a mean of
2280
lb—15
passengers. So,
15
adult male passengers can have a mean weight of up to
2280/15=152 pounds.
If the elevator is loaded with
15
adult male passengers, find the 152
lb. (Assume that weights of males are 161 lb
and a standard deviation of
25 lb.)
Does this elevator appear to be safe?The probability the elevator is overloaded is
nothing.
(Round to four decimal places as needed.)
Does this elevator appear to be safe?
No, there is a good chance that
15
randomly selected people will exceed the elevator capacity.Yes, there is a good chance that
15
randomly selected people will not exceed the elevator capacity.No,
15
randomly selected people will never be under the weight limit.Yes,
15
randomly selected people will always be under the weight limit.
