The drawing of a machined part requires that a feature is machined to 5mm +/-.5mmSix finished parts are measured at: 5.2mm,4.9mm,5.1mm, 5.0mm,4.8mm, and5.1mm. a. Find the mean of the measured parts. b. Find the standard deviation. c. Find the capability Cpk of the machining process. Calculate the sample size n required for a 90% confidence interval that ourCsample mean is within ,1mm of the population mean. (From the standarddeviation tables,z=1.645 for 90% confidence.)
