Prepare a Report Comparing the Sales Volumes and Consistency of Sales of the Four Sales Persons. You are employed as a statistician for a company that makes household products, which are sold by part-time salespersons who work during their spare time. The company has four salespersons employed in a small town. Let us denote these salespersons by A, B, C, and D.
The sales records (in dollars) for the past 6 weeks for these four salespersons are shown in the table below.

Your supervisor has asked you to prepare a brief report comparing the sales volumes and the consistency of sales of these four salespersons. Use the mean sales for each salesperson to compare the sales volumes. Choose an appropriate statistical measure to compare the consistency of sales.
