Question

An elevator has a placard stating that the maximum capacity is 1200 lblong dash8 passengers.​ So, 8 adult male passengers can have a mean weight of up to 1200 divided by 8 equals 150 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 150 lb.​ (Assume that weights of males are normally distributed with a mean of 160 lb and a standard deviation of 33 lb​.) Does this elevator appear to be​ safe? The probability the elevator is overloaded is nothing. ​(Round to four decimal places as​ needed.)
