THIS IS ALL ONE QUESTION

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. The process capability ratio, Cp, of the operation is: Less than 1 Greater than or equal to 1 but less than 1.25 Greater than or equal to 1.25 but less than 1.5 Greater than or equal to 1.5 but less than 1.75 Greater than or equal to 1.75 but less than 2 Greater than or equal to 2 7 point Refer to Scenario B. The process capability index, Cpk, of the operation is: Less than 1 Greater than or equal to 1 but less than 1.25 Greater than or equal to 1.25 but less than 1.5 Greater than or equal to 1.5 but less than 1.75 Greater than or equal to 1.75 but less than 2 Greater than or equal to 2 8 point Refer to Scenario B : 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 capability for Cpk? Check all that apply, and assume the process mean remains unchanged from the original problem. .005.015.025.035.045.055
