7. The City Square Grocery and Meat Market has a large meat locker in which a constant temperature of approximately 40' F should be maintained. The market manager has decided to construct an R-chart to monitor the temperature inside the locker. The manager had one of the market employees take sample temperature readings randomly five times each day for 5 days, when the process was believed to be in control. Following are the temperature sample observations. Sample 1 Temperature(F) 46.3 48.1 42.5 43.1 39.6 41.2 40.5 37.8 36.5 42.3 40.1 41.3 34.5 33.2 36.7 42.3 44.1 39.5 37.7 38.6 35.2 38.1 40.5 39.1 42.3 (a) (2 pts] Compute the sample range for each sample and R. Round your answers to one decimal place.
