Lower Control Limit (LCL;) = inches (round your response to three decimal places). Based on the x-chart, the wire cutting process has been (1) 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 (2)
