Which of the following charts is appropriate to control the number of flaws? P Chart or C Chart? Based on your choice on the last question, calculate “one” of the followings: P (for P chart), or C (for C chart) If you chose P Chart, how much is standard deviation of p (sigma_p)? (Leave empty if you are not doing P chart) Upper Control Limit: Lower Control Limit: I s the number of flaws in control? Yes or No
