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 Rinches (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? 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 Range (in.) Sample Sample Mean (in.) Range (in.) 1 2 3 4 5 6 Sample Mean (in.) 13.804 13.804 13.793 13.808 13.799 13.799 0.044 0.051 0.042 0.037 0.048 0.053 7 8 9 10 11 12 13.803 13.805 13.797 13.801 13.801 13.806 0.021 0.058 0.039 0.038 0.054 0.061 For the given data, the x = 13.802 inches (round your response to four decimal places)
