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 x Hour R Hour X x 1 2 3 4 5 6 3.35" 3.20 3.22 3.29 2.97 2.96 R 0.65" 1.13 1.48 1.31 1.12 0.32 7 8 9 10 11 12 x 3.15" 2.75 2.92 2.75 2.83 2.97 0.58" 1.18 0.66 1.33 1.12 0.45 13 14 15 16 17 18 3.01" 2.93 3.02 2.74 2.76 2.84 0.90" 1.36 1.11 0.45 1.43 1.24 Hour 19 20 21 22 23 24 3.31" 2.99 2.75 3.38 2.94 2.64 R 1.61" 1.09 1.08 0.41 1.53 0.92 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).
