A lab process has an average turnaround time of 25.8 minutes and a standard deviation of 1.24 minutes. The nominal (target) value for the process is 25 minutes with an upper specification limit of 30 minutes and a lower specification limit of 20 minutes. The lab director wants to have four-sigma performance for the lab. Write your final answer only (without intermediate steps) for the fill-in-the-blank questions. Use 2-decimal accuracy for the final answer, e.g., 0.12, when necessary. Question 7 (4 points) Saved For the lab process, the process capability ratio (Cp) = 1.34 A Use 2-decimal accuracy for the final answer, e.g., 0.12, when necessary. Question 8 (4 points) Saved For the lab process, the process capability index (Cpk) - 1.13 A/ . Use 2-decimal accuracy for the final answer, e.g., 0.12, when necessary. Question 9 (2 points) Saved Based on the value of Cpk, the lab process meets the four-sigma standard. This statement is false true O cannot tell whether it is true or false; more information is needed
