21. Elevator Loads The maximum load (with a generous safety factor) for the elevator in an office building is 910 kilograms. The relative frequency distribution of the weights of all men and women using the elevator is mound-shaped (slightly skewed to the heavy weights), with mean m equal to 68 kilograms and standard deviation s equal to 16 kilograms. What is the largest number of people you can allow on the elevator if you want their total weight to exceed the maximum weight with a small probability (say, less than .01)?
