Question: 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

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 = 23.50 grams and s = 0.21 grams. The upper and lower specification limits for the output are USL = 24.40 grams and LSL = 22.80 grams. Based on this information, determine and interpret the value of the Process Capability Index for this process.
