An elevator has a placard stating that the maximum capacity is 1680 lb-10 passengers. So, 10 adult male passengers can have a mean weight of up to 1680/10 = 168 pounds. If the elevator is loaded with 10 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 168 lb. (Assume that weights of males are normally distributed with a mean of 178 lb and a standard deviation of 35 lb.) Does this elevator appear to be safe? The probability the elevator is overloaded is (Round to four decimal places as needed.)
