You are the manager of the concession stands at a sporting venue in a large metropolitan city. The venue hosts several events each week, and your concession stands reported a significant profit during the last calendar year. Joe, one of the 20 cashiers, seems to be coming up short in his cash count after each event. As the manager, you are very concerned and want to use data to determine if something is wrong before confronting, Joe.
