An elevator has a placard stating that the maximum capacity is 19201920 lblong dash—1212 passengers. so, 1212 adult male passengers can have a mean weight of up to 1920 divided by 12 equals 160 pounds.1920/12=160 pounds. if the elevator is loaded with 1212 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 160160 lb. (assume that weights of males are normally distributed with a mean of 163 lb163 lb and a standard deviation of 29 lb29 lb.) does this elevator appear to be safe?
