Question
An elevator has a placard stating that the maximum capacity is 2490 lb-15 passengers. So, 15
adult male passengers can have a mean weight of up to 2490 / 15 = 166 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 166 lb. (Assume that weights of males are normally distributed with a
mean of 172 lb and a standard deviation of 26 lb.) Does this elevator appear to be safe?
The probability the elevator is overloaded is
(Round to four decimal places as needed.)
