The population of weights for men attending a local health club is normally distributed with a mean of 184-lbs and a standard deviation of 28-lbs. An elevator in the health club is limited to 32 occupants, but it will be overloaded if the total weight is in excess of 6240-lbs. Assume that there are 32 men in the elevator. What is the average weight beyond which the elevator would be considered overloaded? average weight = lbs What is the probability that one randomly selected male health club member will exceed this weight? P(one man exceeds) = (Report answer accurate to 4 decimal places.) If we assume that 32 male occupants in the elevator are the result of a random selection, find the probability that the evelator will be overloaded? P(elevator overloaded) = (Report answer accurate to 4 decimal places.) If the evelator is full (on average) 2 times a day, how many times will the evelator be overloaded in one (non-leap) year? number of times overloaded = (Report answer rounded to the nearest whole number.) Is there reason for concern? no, the current overload limit is adequate to insure the safety of the passengers yes, the current overload limit is not adequate to insure the safey of the passengers

average weight = lbs
What is the
P(one man exceeds) =
(Report answer accurate to 4 decimal places.)
If we assume that 32 male occupants in the elevator are the result of a random selection, find the probability that the evelator will be overloaded?
P(elevator overloaded) =
(Report answer accurate to 4 decimal places.)
If the evelator is full (on average) 2 times a day, how many times will the evelator be overloaded in one (non-leap) year?
number of times overloaded =
(Report answer rounded to the nearest whole number.)
Is there reason for concern?
- no, the current overload limit is adequate to insure the safety of the passengers
- yes, the current overload limit is not adequate to insure the safey of the passengers
