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 = 17.35 kilograms and s = 0.95 kilograms. The upper and lower specification limits for the output are USL = 20.50 kilo grams and LSL = 14.30 kilograms. Based on this information, determine and interpret the value of the Process Capability Index for this process.
