Question

A simulation model of a retail store was developed to investigate the effects of various marketing strategies. As part of validation efforts, the model is first run under the current marketing strategy for six independent replications and yielded the following average numbers of people in the store: 15.5, 18, 14.5, 19, 16.8, 18.2. The store manager suggests that the average number of customers in the store is 20. Conduct a hypothesis test to evaluate whether the model output is consistent with the manager’s suggestion. Let the significance level be 0.05.

Answer 1

since test statistic(-4.245) falls in rejection region we reject null hypothesis
we have sufficient evidence to reject the claim made by store manager.
