Q4.1 PLEASE PROVIDE HANDWRITTEN SOLUTIONS

A manufacturing firm that produces steel cabinets would like to implement variable control chart in their fabrication metal corporation. Based on the monthly summary of the QC report, the number one cause of rejection is mis-alignment due to wrong diameter. Thus, a variable control chart shall be implemented to monitor the stability of the fabrication process to consistently achieve the standard diameter. Their plan is to visit the power press machine, randomly pick 6 samples and measure their individual diameters. The result of their initial data gathering is shown below: subgroup Xave Xh XI 18.70 1 19.87 22.10 18.08 21.20 17.26 20.63 20.73 20.14 21.57 24.46 19.86 20.62 23.42 19.47 20.07 21.07 18.33 20.80 21.34 19.69 18.06 20.95 16.87 18.65 21.14 16.89 20.92 23.42 18.68 2 3 4 5 6 7 8 9 10 subgroup 12 13 14 15 16 17 18 19 20 Xh XI Xave 21.65 24.37 18.96 21.85 22.28 20.15 21.47 23.67 19.99 21.53 22.64 18.07 20.14 23.06 18.76 20.51 22.85 18.87 20.74 23.43 18.25 19.04 20.44 18.01 19.72 22.88 17.97 18.30 21.66 15.84 Note: Xaverage = the average measurements for the 6 samples per subgroup, Xh= the highest measurement of the 6 samples, XI = the lowest measurement of the 6 samples taken 1.
