THANK YOU IN ADVANCED

Based on the sampling done, the control limits for 3 sigma x chart are (round all intermediate calculations to three decimal places before proceeding with further calc Upper Control Limit (UCLX)= inches (round your response to three decimal places). Lower Control Limit (LCL)= inches (round your response to three decimal places). Based on the x-chart, the wire cutting process has been The control limits for the 3-sigma R-chart are (round all intermediate calculations to three decimal places before proceeding with further calculations): Upper Control Limit (UCLR)= inches (round your response to three decimal places). Lower Control Limit (LCLR)= inches (round your response to three decimal places). Based on the R-chart, the wire cutting process has been \begin{tabular}{cccc} \hline Sample Size, n & Mean Factor, & Upper Range, & Lower Range, \\ \hline 2 & A2 & D4 & D3 \\ 3 & 1.880 & 3.268 & 0 \\ 4 & 1.023 & 2.574 & 0 \\ 5 & 0.729 & 2.282 & 0 \\ 6 & 0.577 & 2.115 & 0 \\ 7 & 0.483 & 2.004 & 0 \\ 8 & 0.419 & 1.924 & 0.076 \\ 9 & 0.373 & 1.864 & 0.136 \\ 10 & 0.337 & 1.816 & 0.184 \\ 12 & 0.308 & 1.777 & 0.223 \\ \hline \end{tabular}
