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 1 2 3 4 5 6 X 3.35" 3.10 3.12 3.39 2.97 2.76 R 0.71" 1.13 1.43 1.21 1.22 0.37 X X 4.51" 2.99 Hour X R Hour R Hour 7 3.05" 0.53" 13 3.01" 0.80" 19 8 2.75 1.18 14 2.93 1.26 20 3.02 0.71 15 3.02 1.01 21 2.55 10 2.95 1.28 16 2.74 0.45 22 3.28 11 2.73 1.12 17 2.76 1.43 23 12 2.97 0.35 18 2.74 1.29 24 9 R 1.66" 1.14 1.08 0.41 2.94 1.63 2.54 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) = 3.745 inches (round your response to three decimal places). Lower Control Limit (LCL) = 2.269 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): Upper Control Limit (UCLR) = inches (round your response to three decimal places). |

Reter 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: Based on the sampling done, the control limits for 3 -sigma x chart are (round al infermedate calculatons to three decimal places before aroceeding with further calcula5ons) Upper Control Limit (UCL-) = 3745 inches (round your response to three decimal places). Lower Centrol Limir ( (Cl)=2269 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-sigme R-chart are (round all intermedate caloulations to three decimal places before proceeding with further calculasons): Upper Control Limit (UCLR)= inches (round your respanse to three decimal places)
