Refer to Table 56.1-Factors for Computing Control
Refer to Table 56.1-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 IN CONTROL x R 3.25* 0.76* 3.10 1.13 3.12 1.48 3.29 1.31 3.07 1.22 2.76 0.32 12 3.07 Hour R 3.21" 0.90* 19 2.73 1.26 Hour X R Hour X 7 2.95 0.58 13 8 2.65 1.13 14 9 3.02 0.71 15 10 2.95 1.38 16 11 2.73 1.22 17 2.76 1.38 0.45 18 2.64 1.29 3.22 1.11 2.74 0.55 OUT OF CONTROL ax X 3.41" 20 2.99 2.55 22222 21 23 R 1.661 1.09 1.13 3.28 0.51 2.84 1.63 2.74 0.92 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 (UCL) - inches (round your response to three decimal places).
