When rating elevator capacity, it is common to use a 25% safety factor, so an elevator should be able to carry 125% of the rated limit. So if an elevator is rated at 2500 lbs. and 16 male passengers get in the elevator, with a mean weight of 195.3 lbs. what is the probability that the elevator is truly overloaded? ( mean weight of all males is 182.9 lbs with a standard deviation of 40.8)
