Scenario EO. A woodcutting operation has a target (nominal) value of 200 inches and consistently averages 200.1 inches with a standard deviation of .05 inches. The design engineers have established an upper specification limit of 200.25 and a lower specification limit of 199.75 inches. Refer to Scenario E0. Suppose the company wants to improve its capability to a 5-sigma level by reducing the variability of its process. Which of the following standard deviations would meet a 5-sigma capablity for Cpk? Check all that apply, and assume the process mean remains unchanged from the original problem. .005 .015 .025 .035 .045 O .055
