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 20 Hour X 3.35" 3.10 3.32 3.39 3.17 2.86 R 0.76" 1.23 1.43 1.31 1.12 0.32 0.32 Hour X 7 2.95" 8 2.75 9 3.12 10 2.75 11 2.73 12 2.87 R 0.48" 1.18 0.66 1.33 1.17 0.45 Hour X 133.21" 14 2.83 153.22 16 2.74 | 17 2.76 18 2.84 R 0.90" 1.26 1.11 0.55 1.48 1.34 x 4.51" 2.89 2.55 3.28 2.84 2.74 R 1.56" 1.14 1.13 0.46 1.58 1.02 2 4 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) = 3.791 inches (round your response to three decimal places). Lower Control Limit (LCL) = 2.274 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).
