Please answer question 18, it may or may not have multiple answers! I will upvote if so

Question 16 1 pts SCENARIO A A woodcutting operation has a targer (nominal) value of 3 inches and consistently everages 21.1 inches with a standard deviation of D5 inches. The design engineers have established an upper specification limit of 2.XI.25 and a lower specification limit of 199.95 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 multa 1.5 but less than 1,75 Greater than or equal to 125 but less than 2 Greater than or equal to Z Question 17 1 pts Releri SA 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 15 but less than 1.75 Greater than or equal to 1.75 but less than 2 Greater than or equal to 2 Question 18 1 pts Refer to Scenario A 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.
