(d) A C-chart 7. The City Square Grocery and Meat Market has a large meat locker in which imately 40 F should be maintained. The market manager has temperature of approximately 40 F should be maintained Fruct an R-chart to monitor the temperature inside the locker. The decided to construct an R-chart to monitor the tem manager had one of the market employees take sample temperature readings random fismetimes each day for 5 days, whenthe process was believed to be in control Following are the temperature sample observations.

Round your answers to one decimal place. Use the following chart for your computation
