2. Assume that 9 IC observations have been collected for phase II monitoring of a production process. These observations along with the first 21 phase II observations are presented below. 11.528, 8.990, 9.590, 9.648, 16.807, 14.850, 10.708, 7.042, 5.427, 10.107, 0.029, 9.836, 6.807, 12.428, 18.920, 7.535, 11.330, 3.883, 8.874, 16.850, 9.627, 10.887, 21.789, 12.482, 12.741, 13.236, 18.913, 15.113, 16.006, 17.006 Use the CPD control chart to monitor the process mean (hint: you can use the recursive equations in the slides). In the control chart, use alpha = 0.05, and you can determine the control limit Hn computed by the approximation formula based on Hawkins et al. 2003 as discussed in the slides.
