The next two questions are based on this scenario. Note that the M/M/1 model assumptions are NOT valid for this situation. Also, since it is closing time, we are limiting the number of arrivals to four, while still following the FIFO assumption. Hence, the default assumption of unlimited arrivals don't hold. The following table (Table 1) shows the results of a mini simulation of a queue with four customers. For this problem, assume that the simulation used 10:02 PM as the starting time and that there is only a single employee working continuously (no breaks) until all four customers are served. We also assume that the employee does not serve the next customer until the previous customer is served. Table 1: Queue Information for the first four customers served Customer Number Arrival Time Service Time Service Ends 1 10:02 PM 7 10:09 PM 2 10:08 PM 9 10:18 PM 3 10:16 PM 11 10:29 PM 4 10:27 PM 9 10:38 PM What is the average wait time (in queue) for a customer
