You finished your degree and found your dream job working for a non-profit as the assistant executive director. Your boss asks you to review the staffing schedule for the clinic your organization runs. The previous assistant director justified higher staffing on Friday and Saturday saying that the number of clients rose on these days. You do not believe this to be true and feel the numbers are the same as you would see for any of the last 4 days of the week. (Equal number each day) Before you adjust the schedule and upset the employees by cutting the number on Friday and Saturday, you decide to run a Chi Square goodness of Fit test. That way you will have evidence to present to the director if you implement the cut in hours. Test the claim that there is no difference at the .01 significance level. Can you implement your staffing changes?
