A machining process produces metal pins with a target diameter of 10.00 mm. The specification limits are LSL = 9.90 mm and USL = 10.10 mm. A sample of 30 parts shows a mean of 10.02 mm and a standard deviation of 0.025 mm. Question: Compute Cp and Cpk. Based on your results, determine whether the process is capable of meeting specifications.
