Refer to Table 56.1 - Factors for Computing

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 1 1 2 Sample Mean Range (in.) Sample Sample Mean (in.) Range (in.) (in.) 10.904 0.033 7 10.903 0.041 10.900 0.041 8 10.903 0.034 10.893 0.034 9 10.893 0.027 10.904 0.051 10 10.901 0.029 10.897 0.031 11 10.903 0.039 10.897 0.036 12 10.904 0.047 3 4 5 6 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 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
