An elevator has a placard stating that the maximum capacityis
16201620
lblong dash—1010
passengers.​ So,
1010
adult male passengers can have a mean weight of up to
1620 divided by 10 equals 162 pounds.1620/10=162 pounds.
If the elevator is loaded with
1010
adult male​ passengers, find the probability that it isoverloaded because they have a mean weight greater than
162162
lb.​ (Assume that weights of males are normally distributed witha mean of
171 lb171 lb
and a standard deviation of
26 lb26 lb​.)
