2. A metal fabricator produces connecting rods with an outer diameter that has a 1 ± .01-inch specification. A machine operator takes several sample measurements over time and determines the sample mean outer diameter to be 1.002 inches with a standard deviation of .003 inch. a. Calculate the process capability index for this example. b. What does this figure tell you about the process?
