The file P20_01.xlsx contains data on the amount of soda (in ounces) placed in aluminum cans by a particular filling process. Ideally, the filling process should place 12 ounces of soda in each can. Every hour, 4 cans of soda were randomly selected from the production process and measured for amount of fill. This was repeated for 25 consecutive hours. Generate and interpret X and R charts for the given data. Does this filling process appear to be in control?
