Interpret the process capability index

Reference no: EM13975124

1. Given the conclusion reached in the solution for Exercise 20.75, with the data in file XR20075, is it appropriate to compute the Process Capability Index (Cpk) for this process? If so, determine the overall mean and standard deviation for all the units measured, then compute and interpret the Process Capability Index if the specification limits are USL 5 33.700 pounds and LSL 5 21.700 pounds.
