An elevator has a placard stating that the maximum capacity is 2505 lb15 passengers.So, 15 adult male passengers can have a mean weight of up to 2505/15=167pounds. If the elevator is loaded with 15 adult malepassengers, find the probability that it is overloaded because they have a mean weight greater than 167 lb.(Assume that weights of males are normally distributed with a mean of 170lb and a standard deviation of 33lb.) Does this elevator appear to besafe?
