14. 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 2 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 3 4. (a) [2 PTS] Compute the sample range for each sample and R. Round your answers to one decimal place. Sample Range 1 Sample Temperature(° F) 16.3 39.6 | 11.2 10.5 36.5 12.3 3 | 10.1 11.3 31.5 33.2 36.7 12.3 11.1 39.5 37.7 38.6 5 35.2 38.1 10.5 39.1 12.3 (b) (2 PTS) Compute the upper control limit and the hour
R- (b) (2 PTS] Compute the upper control limit and the lower control limit for the R- chart. Round your answers to one decimal place. Use the following chart for your computation.
