Task 4: Eight samples of 80 kg concrete slabs produced by a machine are collected. (Observations are provided in the following table): Sample: 1 3 4 6. 7 8 79.2 77.5 79.6 78.9 80.5 79.7 79.6 78.9 78.8 78.7 79.4 79.4 79.6 80.6 79.6 80.9 79.9 81.2 80.3 79.6 80.3 80.4 80.4 78.7 If the weight specification limits for a slab are 78.5kg (LSL) and 81.5kg (USL), what is the Cpk? Is the production process capable? Why (not)? b. Using A2, D3 and D4 factors, determine the upper and lower control limits for sample mean and sample range, and decide if the process is in control. State the reason for your decision. a. (Please use Excel for accurate results. Round final answers to 4 decimal places.) Observations
