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 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.) 1 7 2 8 Sample Mean (in.) 12.104 12.100 12.093 12.106 12.099 12.097 Range (in.) 0.044 0.051 0.042 0.037 0.048 0.053 3 9 12.103 12.105 12.097 12.101 12.101 0.021 0.058 0.039 0.038 0.054 0.061 4 10 5 11 6 12 12.108 For the given data, the x = 12.1 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). For the given data, the x = inches (round your response to four decimal places). Based on the sampling done, the control limits for 3-sigmax 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
