Question 4 [20 marks] By utilising Annexure A, answer the following questions: (a) 15 samples of n 8 have been taken from a cleaning operation. The average sample range for the 20 samples was 0.016 minute, and the average mean was 3 minutes. Determine the three-sigma control limits for this process. (4 marks) (b) 15 samples of n 10 observations have been taken from a milling process. The average sample range is 0.01 centimetres. Determine upper and lower control limits...
Using Minitab, solve the following problem. A process that produces parts for auto-mobile turbocharger wheels is to be controlled though the use of a fraction nonconforming chart.
