Question: You are responsible for planning the layout of a new parking lot for a company with 200 employees. Employees are urged to car pool. From the local chamber of commerce you learn the -average number of workers in daily car pool is 2.3."

(A) Explain why "2.3" cannot be the median for the variable "average number of workers in a daily car pool."

(B) For a variety of reasons, only 91% of the workers actually come to work each day. How many parking spaces are needed for employee parking?

(C) Suppose the mean commute for each car pool is 19.6 miles with a standard deviation of 5.3 miles and the commuting distance is independent of the car pool chosen. If the distribution of miles commuted is normal, what is the probability that 2 car pools chosen at random each had a commute greater than 22 miles?
