“b) The measurements above represent the mean diameter of a turned shaft. Quality data has been logged and the following statistical data has been extracted. Sample standard deviation, taken from the analysis of 20 data sets, each having sample sizes of 10 units: 0.03 mm
Process Mean Diameter (from the sample sets): 14.96mm
Given that the nominal diameter (per print) is 15.00mm +/-0.10mm, what can be said about the expected defect rate?
