7 Go to four decimal places in all calculations. Problem 3 is worth 60 points below 3. There is a lawn mower used to cut a putting green. The putting green needs to be 653 inch long with a tolerance of +/- 1.50 inches The lawn mower that mows the lawn has a mean of 7.70 inches with a standard deviation of 0.130 inches. Compute the process capability ratio (Cp) and the process capability index (Cpk). 3a.) Cp = 10 pts answer, (Go to 4decimal places), place answer on this line, show your work on next page. I want a number here, not a word. 3b.) Cok= 15 pts answer (Go to 4 decimal places), place answer on this line, show your work on next page. I want a number here, not a word. [hint Cok, is not zero. Zero is not the answer] 3c.) Does the process meet 6 sigma quality? (yes or no). 3 pts answer 3d.) If not, then does the standard deviation have to be changed? In other words; is the "Cp" value not O.K? If Cp is not O.K., then your answer would be yes. If "Cp" is O.K. then answer would be no fyes or no). 3 pts answer 3e.) If standard deviation has to be changed, what does it have to be changed to? 2 pts ans 3f.) If process does not meet 6 sigma, does the mean have to be changed? In other words, is the Cpk value not O.K. If it is not O.K.; then your answer would be yes. If Cok is O.K. answer would be no. (yes or no). Ans. 2.0pts 3g2If mean has to be changed, what does the mean have to be changed to in order to achieve six sigma quality. 25 pts answer (go to four decimal places), place answer on this line, show your work on next page.
