Please calculate control limits for highlighted

Refer to Table S6.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. Sampling 4 pieces of precision-cut wire (to be used in computer assembly) every hour for the past 24 hours has produced the following results: Hour R X 1 2 3.35" 3.20 3.32 3 R Hour R X Hour X Hour 0.71" 7 2.95" 0.48" 13 3.21" 0.80" 19 1.13 8 2.55 1.18 14 2.73 1.31 20 1.38 9 3.12 0.76 15 3.02 1.11 21 1.21 10 2.75 1.28 16 2.74 0.55 22 1.17 11 2.93 1.22 17 2.86 1.38 23 0.37 12 3.07 0.45 18 2.84 1.29 24 4 3.49 5 3.17 6 2.86 Based on the sampling done, the control limits for 3-sigma x chart are (round all intermediate calculations to three decimal places before proceeding Upper Control Limit (UCL) = 3.79 inches (round your response to three decimal places). Lower Control Limit (LCL-) = 2.29 inches (round your response to three decimal places). Based on the x-chart, the wire cutting process has been OUT OF CONTROL The control limits for the 3-sigma R-chart are (round all intermediate calculations to three decimal places before proceeding with further calculations) (round your response to three decimal places).
