10. An American Hospital Association survey found that most hospital emergency rooms are operating at full capacity (Associated Press, April 9, 2002). The survey collected data on the emergency room waiting times for hospitals where the emergency room is operating at full capacity and for hospitals where the emergency room is in balance and rarely operates at capacity. Sample data showing waiting times in minutes are as follows.

a. Compute the mean and median emergency room waiting times for hospitals operating at full capacity.

b. Compute the mean and median emergency room waiting times for hospitals operating in balance.

c. What observations can you make about emergency room waiting times based on these results? Would the American Hospital Association express concern with the statistical results shown here?
