The production manager at Sunny Soda, Inc. is interested in tracking the quality of the company’s 12-oz bottle filling line. The manager collected 15 samples of 4 bottles each and calculated the overall mean filling was 12.001 oz and the overall range was 0.1267 oz. (This is based on raw sample data. I have performed the calculations for the X-double bar and R-bar to save you time.) For each of the charts you identified above, what are the values of the centerline, UCL and LCL?
