For staffing purposes, a retail store manager would like to standardize the number of checkout lanes to keep open on a particular shift. She believes that if the standard of the hourly customer arrival rates is 8 customers or less, then a fixed number of checkout lanes can be staffed without excessive customer waiting time, or excessive clerk idle time. However, determining how many checkout lanes ( and thus clerks) to use, she must verify that the standard deviation of the arrival rates does not exceed 8. Accordingly, a sample of 25 hourly customer arrival rates was complied for that shift over the past week. a. State the hypothesis to test wether the standard deviation of the customer arrival rates exceeds 8.b. Calculate the value of the test Statistic. Assume that customer arrival rates are normally distributed. c. Use excels function (CHISQ. DIST. RT or CHISQ. DIST) to compute the p-value. d. At a=0.05, What is your conclusion? Would your conclusion change at the 1% significance level?
