A small service firm responds to walk-in customers who arrive on average, every 24 minutes. During one shift, the firm is staffed by a relatively new and somewhat inexperienced employee. This employee currently has an average service time of 10 minutes per customer. Assuming Poisson arrivals and exponential service times, and using your knowledge of queuing theory, answer the following questions. Points possible on the following questions are: 1a) 5, 1b) 5, 2c) 5, 2di) 5, 2dii) 5Ideally, the firm desires that the average waiting time for a customer is less than five minutes. Calculate the average wait in queue, provide your numerical result, and explain whether the objective of average wait time of less than five minutes will or will not be satisfied.Calculate the average length of the waiting line, provide your numerical result. Then answer the following: If the firm desires to have no more than one person waiting, will this goal be accomplished On average?Always?

All exams are closed note and closed book. No reference materials are allowed, except students may use one page (one side of one 8.5 x 11 sheet of paper) of hand-written formulas. Some questions require analysis using Microsoft Excel to perform necessary calculations, therefore, it is acceptable to use that software on the computer.
