Question: 1. What is the standard deviation (sigma) for the X bar chart? The R chart? 2. What would be the 3 sigma upper and lower

1. What is the standard deviation (sigma) for the X bar chart? The R chart? 2. What would be the 3 sigma upper and lower control limits for all 28 observations? On a separate sheet, type brief answers to the following questions: 3. Does it appear to matter what type of flour was used? How can you tell? 4. Would it help to chart the cookies made with Baker flour apart from those made with Acme? 5. What is the sigma now (once separated)? 6. What recommendations would you make for further improving this process and thereby improving the quality of the output? Turn in X-bar and R charts to support your case.
