Texts: The
At a time, a boat can stop for gas and servicing simultaneously. Assume that the
arrival rate of boats at the dock is 0.8 boats per hour. (Round your answers to four decimal places.)
(a) What is the probability that the boat dock will be idle? 0.2000
(b) What is the average number of boats that will be waiting for service? 0.6400
(c) What is the average time (in hours) a boat will spend waiting for service? 0.1600 hours
(d) What is the average time (in hours) a boat will spend at the dock? 0.2400 hours
Yes, since the average time a boat will spend at the dock is less than 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 exceeding 10 minutes. Is enlarging the capacity of the dock to handle two boats at a time a good way of achieving this? No, enlarging the capacity of the dock may not be the best way of achieving their goal.
