1. Calculate the control charts (UCL, CL, and LCL) for each operator machine combination separately. needs to be completed for both X-Bar (Average) and R-Bar (Range) charts. Draw conclusions from the charts about each operator-machine combination

2. What should be done based on the calculations from Question 1?

3. What is the process capability for each operator-machine combination?

4. Can you be sure that all the parts produced by in-control processes will meet the specifications? Why or why not?

5. Identify and explain any underlying assumptions for the calculations done here.
