A crew of mechanics at the Center Rear Department repair copiers that break down at an average of 5 copiers per day (approximately Poisson in nature. The mechanic crew can service an average of 6 copiers per day with a repartite distribution that approximates an exponential distribution. The crew cost is approximately $300 per day. The cost associated with lost productivity from the breakdown is estimated at $200 per copier per day (or any traction thereof). a. What is the expected cost of this system? Which is cheaper, the existing system with one service crew or a revised system with two service crews? Given that the average number in the queue (LQ) is 0.1751 and the average number in the system (Ls) is 1.0084] 0 points) A state department of tourism and recreation collects data on the number of cars with out-of-state license plates in a state park. (The group's position is that more out-of-state plates means that the state's advertising programs are working.) The sample size is fixed at n=100 each day. Data from the previous 10 days indicate the following number of out-of-state license plates: Day Out-of- state plates 20 Out-of- state plates 18 21 36 12 37 10 Y=22,1 a. Calculate the overall proportion of tourists" (cars with out-of-state plates). . Calcalde une LGL and UCL for these data. c. Is the advertising campaign having an effect? Explain why or why not.
