A company produces a part that goes into precision testing equipment. The specifications for the part are 8.0003.000 millimeters. Management is concerned about the capability of the process to produce that part. The following data were randomly collected during test runs of the process: (a) Construct an R - and an x-chart for this process. Is the process in statistical control? (b) Suppose that the standard deviation of the process distribution is 0.851 . Is the process capable of producing the part at the three-sigma level? Why or why not? If not capable, is the problem variability or the centering of the process?
