An elevator has a placard stating that the maximum capacity is 1630
1630 lblong dash
10
10 passengers.So, 10
10 adult male passengers can have a mean weight of up to 1630 divided by 10 equals 163 pounds.
1630/10=163pounds. If the elevator is loaded with 10
10 adult malepassengers, find the probability that it is overloaded because they have a mean weight greater than 163
163 lb.(Assume that weights of males are normally distributed with a mean of 171 lb
171lb and a standard deviation of 33 lb
33lb.) Does this elevator appear to besafe?
The probability the elevator is overloaded is
nothing
.
(Round to four decimal places asneeded.)
