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 Hour Hour R Hour X R 0.65" 1.13 1 2 3 4 13 14 x 3.35" 3.10 3.22 3.39 3.07 2.96 7 8 9 1.38 x R 3.05" 0.58" 2.55 1.08 3.12 0.66 2.95 1.38 2.73 1.22 3.07 0.45 15 x 3.01" 2.73 3.12 2.74 2.76 2.64 0.85 1.36 1.01 0.55 1.43 1.29 19 20 21 22 23 3.31" 2.79 2.55 3.38 3.04 2.74 1.61" 1.14 1.13 0.41 1.53 1.02 16 5 6 1.21 1.17 0.37 10 11 12 17 18 24 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 calculations): Upper Control Limit (UCL;) - 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
