The average processing time required for a product is computed automatically by the drilling machine is approx. 90 seconds. The output were collected from the simulation for three runs of 10 products each, with these results: Value Replication 1 2 3 4 5 6 7 8 9 10 1 89.77 90.20 89.28 90.62 90.00 90.32 90.30 90.27 90.04 90.67 2 89.27 90.66 89.19 89.43 90.25 90.35 90.28 89.89 90.46 89.98 3 90.64 90.04 90.46 89.78 90.28 90.35 90.14 90.32 90.56 90.07 a) Determine the 95% confidence interval to evaluate whether model output is consistent with system behavior. (10 pts) b) Determine the warm-up period with the moving average window w = 1. (10 pts)
