5. Conduct a bank simulation (poisson arrivals and exponential service time distribution) for an utilization of p = 0.6 and for 8000 customer arrivals by running the single server Java code that you used before. Assume the average service time is 2 minutes. Run 10 replications of the same simulation (i.e., p= 0.6) by changing the initial seed and observe the total delay experienced by the customers. a. What are the point estimator, confidence interval and prediction interval for this delay? Assume a 0.05 b. If real system's validation (measured) data reveals that the average delay experienced by customers is 5 minutes, is simulation data consistent with system behavior? Use a and = 0.5 minutes. = 0.05 c. Repeat the above with 40000 customers. What differences did you observe between these experiments?
