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 Hour 19 R 1.56" 1.14 R 0.76" 1.23 1.43 1.31 1.12 0.32 Hour 7 8 9 10 11 12 3 3.35" 3.10 3.32 3.39 3.17 2.86 R 0.48" 1.18 0.66 1.33 1.17 0.45 Hour 133.21" | 14 2.83 153.22 16 2.74 17 2.76 18 2.84 2.95" 2.75 .12 2.75 2.73 2.87 21 R 0.90" 1.26 1.11 0.55 1.48 1.34 1.13 4.51" 2.89 2.55 3.28 2.84 2.74 0.46 1.58 1.02 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-) = 1 inches (round your response to three decimal places). * Definition Sample Size, n Upper Range, Lower Range, D4 D3 Mean Factor, A2 1.880 1.023 0.729 0.577 0.483 0.419 0.373 0.337 0.308 0.266 OOO 3.268 2.574 2.282 2.115 2.004 1.924 1.864 1.816 1.777 1.716 0.076 0.136 0.184 0.223 0.284
