from simulation with arena 6th edition

Exercise (6-2) Using the model from Exercise 5-2, change the processing time for the second pass on Machine 1 to TRIA(6.7, 9.1, 13.6). Run the simulation for 20,000 minutes and compare the results with respect to the same three output performance measures. Do an informal statistical comparison by making 20 replications of both versions of the model, forming 95% confi dence intervals, and looking at the relation between the confi dence intervals.
