A metal fabricator is looking at the outer diameter of connecting rods that have been produced. The design specifications for these connecting rods call for an average of 1.0 inch, with a lower specification limit 0.99 inch and an upper specification limit 1.01 inch. A machine operator takes several sample measurements over time and determines the process mean outer diameter to be 1.002 inches with a standard deviation of .0035 inch. (a) Calculate the process capability index for this problem. (Round the answer to two decimals) (b) Is this process capable of meeting design requirements or not? Provide your reason. (b) What is the percentage of good parts? (Round the answer to two decimals)
