For the problem stated above the control limits are the following: (a) For Mean weight the answer is LCL = 9.6605 ounces and the UCL = 10.3895 ounces. Next, (b) For Range the answer is LCL = 0 and the UCL = 1.141 ounces. My conclusion is that the process from the calculations seems to be in control. I believe this is the case since there are no indicating points lying outside the control limits. If you look at both x-bar chart and R chart, you can draw this conclusion. Therefore, the process seems to indicate that it is in control.
