3. Suppose an elevator has a maximum capacity of 16 passengers with a total weight of 2500 lb. Assume that weights of women are normally distributed with a mean of 143 lbs and a standard deviation of 29 lbs.

a. Find the probability that 1 randomly selected woman has a weight greater than 156.25 lb.

b. Find the probability that a sample of 16 women have a mean weight greater than 156.25 lb (which puts the total weight at 2500 lb, exceeding the maximum capacity).

The elevator in the car rental building at San Francisco International Airport has a placard stating that the maximum capacity is ``4,000 lbs---27 passengers.'' Because 4000/27=148, this converts to a mean passenger weight of 148 lbs when the elevator is full. We will assume a worst-case scenario in which the elevator is filled with 27 adult males. Assume that adult males have weights that are normally distributed with a mean of 189 lbs and a standard deviation of 39 lbs....

An elevator has a placard stating that the max capacity is 2028lb- 12 passengers. So, 12 adult males passengers can have mean weight up to 169lbs. If the elevator is loaded with 12 adult males, find the probability that it is overloaded because they have a mean weight greater than 169lb. Assume weight of males normally distributed with a mean of 175lb and standard deviation of 27lb. Does this elevator appear to be safe? How can I solve this using...
