After seeing that your measurement system at final test was not acceptable, you developed written procedures for the final test process, trained all inspectors in it, and conducted another MSA to determine whether the final test measurement system is now acceptable. The new MSA showed total Gage R\&R variation at 8.52% of total, so this proved that you are now capable of accurate measurements at final test. Your next goal is to verify the defect rate that TT is reporting to you. To do this, you know you must have a stable process, so you monitor the process and collect 25 days of data on the dimension your Pareto chart showed to be the highest failing dimension on the lens purchased by TII. Fortunately, the control chart was found to be stable and normally distributed with an average thickness of 0.2817 inches and a standard deviation of 0.013 inches, 50 you can now accurately calculate the baseline process performance indices for this dimension. It has an upper specification limit. of 0.3 inches and a lower specification limit of 0.25 inches. Question \#1: What is the baseline Pp for this dimension, and is it acceptable? Explain your answer. (Round your final answer to 2 decimal places but don't round any of the values given to youl) SHOW YOUR WORKI Is this Pp acceptable? Explain your answer. Question \#2: What is the baseline Ppk for this dimension, and is it acceptable based on commonly accepted values? (Round your final answer to 2 decimal places but don't round any of the values given to youl) SHOW YOUR WORKI Is this Ppk acceptable? Explain your answer. Question \#3: Use the Ppk to estimate the sigma level for this dimension. SHOW YOUR WORKI
