           b. What are the upper and lower control limits for the process range? (Input the correct formula in the worksheet.)
           c. Plot the control chart for the process mean. Is the process mean in control? Explain.
           d. Create the plot for the process range control chart. Is the process range in control? Explain.

5. Create a Process Chart for Problem 7.2d (p282) using the case given below, with five columns of chart symbols, process description column, and no "Distance in Feet" or "Time in Minutes" columns:

Requirements
Individual Items: Be prepared to present your solution any class after the homework Item is assigned. For computerized problems, bring solution printout and flash drive to demo solution on the PC to the class.

At the professor's discretion, the class may be requested to submit their solutions during the first 2:00 minutes of class.  After review by professor, students will volunteer, and one will be selected for presentation. 

Your grade for the Presentation of Homework Exercises is based on having an honest written attempt at the solution and volunteering to present.  For each problem that you are not appropriately prepared and you do not volunteer, your grade is reduced by 10%.

(You may think of these Homework Exercises as take-home quizzes.)

Entire Homework Set: This problem set is to be complete and professional looking. As a result, your solutions must show all work, not just the answer. An additional cover or binding is not required nor desired, but the problem set is to be stapled (not paper clipped) together as one unit in sequential order. If not, penalty is 10%. No photocopies. Each student is to submit their own work (If not, grade on homework is zero).  An additional 20% may be deducted for sloppiness and/or poor English.
