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 R Hour R Hour R R 1 2 3 4 5 6 x 3.15" 3.00 3.22 3.39 2.97 2.86 0.76" 1.18 1.43 1.26 1.17 0.32 7 8 9 10 11 12 x 3.05" 2.55 3.02 2.85 2.73 2.97 0.53" 1.13 0.66 1.38 1.12 0.40 13 14 15 16 17 18 x 3.21" 2.93 3.02 2.74 2.76 2.64 0.80" 1.36 1.06 0.50 1.48 1.34 Hour 19 20 21 22 23 24 3.31" 2.79 2.75 3.18 2.94 2.64 1.61" 1.14 1.03 0.41 1.63 0.97 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).
