Refer to Table 56.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. Twelve samples, each containing five parts, were taken from a process that produces steel rods at Emmanual Kodzi's factory. The length of each rod in the samples was determined. The results were tabulated and sample means and ranges were computed. The results were: Sample Sample Sample Mean (in.) Range (in.) 7 2 3 4 5 6 Sample Mean (in.) 11.102 11.100 11.089 11.106 11.095 11.099 Range (in.) 0.044 0.051 0.042 0.037 0.048 0.053 8 9 10 11.103 11.105 11.093 11.103 11.101 11.108 0.021 0.058 0.039 0.038 0.054 0.061 11 12 For the given data, the x = 11.0985 inches (round your response to four decimal places). Based on the sampling done, the control limits for 3-sigma x chart are: Upper Control Limit (UCL;) - inches (round your response to four decimal places). Lower Control Limit (LCL;) - inches (round your response to four decimal places) Based on the X-chart, is one or more samples beyond the control limits? For the given data, the R = inches (round your response to four decimal places). The control limits for the 3-sigma R-chart are: Upper Control Limit (UCLR) - inches (round your response to four decimal places Lower Control Limit (LCLR) = inches (round your response to four decimal places, Based on the R-chart, is one or more samples beyond the control limits?
