Jiang Sports America manufactures a variety of sport shoes including golf shoes. They are highly responsive and trend-aware. Thus, they look for inspiration for current events. A recent model is based on the Odell Beckham Jr. Nike Vapor Untouchable Pro 3 OBJ Uptempo Cleat with a custom Joker face. For some unknown reason, on any given shoe, some number of the nine (9) cleats is left loose and can fall off during shipping. Due to the high cost of these shoes, customers have been complaining and Jiang Sports America has vowed to correct this production problem. They decide to take samples of 100 pairs of shoes each hour and collect data on loose cleats. Below is a table of 25 data points. Unfortunately, the engineer who designed the data collection scheme has gone hiking on the Pacific Crest Trail and cannot be found or contacted. You are called to a meeting to discover you have been reassigned to this problem. Develop an appropriate control chart and recommend action. Then, what should
