Refer to Table 56.1 - Factors for Computing

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 x Hour x Hour R Hour X R 1 2 3 R 0.71" 1.18 1.48 1.21 1.12 0.37 3.25" 3.20 3.32 3.49 3.17 2.76 7 8 9 3.05" 2.55 3.02 2.85 2.93 3.07 R 0.48" 1.18 0.71 1.33 1.22 0.40 13 14 15 16 17 18 3.21" 2.83 3.22 2.74 2.86 2.64 0.85" 1.36 1.11 0.50 1.43 1.34 19 20 21 22 23 24 3.41" 2.99 2.75 3.18 3.04 2.74 1.61" 1.14 1.08 0.51 1.63 1.02 4 5 6 10 11 12 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 (UCLx) = inches (round your response to three decimal places). Lower Control Limit (LCLz) = 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).
