Assume that the arrival rate is I boats per hour ond that the service rate for each server is ? boats per hour. (Round your answers to four decimal places.) (a) What is the probabitity that the boat dock will be idie? (b) What is the average number of boats that will be waiting for service? (c) What is the average time (in hours) a boat will spend waiting for service? h (d) What is the average time (in hours) a boat will spend at the dock? (d) What is the average time (in hours) a boat will spend at the dock? (e) If customers expect to be able to be in and out of the marina within 10 minutes on average, does this system provide acceptable service? , since the average time a boat will spend at the dock is 10 minutes. (f) The manager of Fore and Aft Marina is interested in balancing good customer service with the cost of providing this service. To achieve this, the manager would like the customer's average time in the system to be as close to 10 minutes as possible, but not excesding 10 minutes.
