Economic Analysis of Waiting Line systems The advertising campaign for Mark's Coffee Shop doubled their business. The mean rate of orders arriving is 40 per hour and they must decide how many servers to hire. Each server can process an order in an average time of 2 minutes. They have determined the average waiting cost per minute for an order to be $.50. Servers hired will earn $20 per hour in wages. o) Using this information compare the total hourly cost of hiring 2 servers with that of hiring 3 servers. The answer is supposed to be $112.00 per hour for 2 servers and $104.35 per hour for 3 servers. Not sure how to get there though...

A New York Times article titled For Runners, Soft Ground Can Be Hard on the Body considered two perspectives on whether runners should stick to hard surfaces or soft surfaces following an injury. One position supported running on soft surfaces to relieve joints that were in recovery from injury. The second position supported running on hard surfaces since soft surfaces can be uneven, which may make worse those injuries a soft surface was intended to help. Suppose we are given sufficient funds to run an experiment to study this topic. With no studies to support either position, which of the following hypotheses would be appropriate? The first position is more sensible, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the second position. The second position makes the more sense, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the first position. Because we would be interested in any…
