Extracted text: An elevator has a placard stating that the maximum capacity is 1580 lb-10 passengers. So, 10 adult male passengers can have a mean weight of up to 1580 /10 = 158 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 156 lb. (Assume that weights of males are normally distributed with a mean of 185 lb and a standard deviation of 30 lb.) Does this elevator appear to be safe? The probability the elevator is overioaded is O (Round to four decimal places as needed.)
