A simulation model of a job shop was developed to investigate different scheduling rules. To validate the model, the scheduling rule currently used was incorporated into the model and the resulting output was compared against observed system behaviour. By searching the previous year's database records, it was estimated that the average number of jobs in the shop was 22.5 on a given day. Seven independent replications of the model were run, each of 30 day's duration, with the following results for average number of jobs in the shop: 18.9 22.0 19.4 22.1 19.8 21.9 20.2 Develop and conduct a statistical test to evaluate whether model output is consistent with system behaviour. Use the level of significant a=0.05. t6,0.025=2.45
