A process is in control and the results from a series of samples show the overall mean and standard deviation of all the units sampled to be x-double bar = 2.320 inches and s = 0.003 inches. The upper and lower specification limits for the output are USL = 2.328 inches and LSL = 2.272 inches. Based on this information, determine and interpret the value of the Process Capability Index for this process.
