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 R Hour R Hour R 13 14 1 2 3 4 5 6 3.25" 3.10 3.22 3.39 3.07 2.86 R 0.71" 1.18 1.43 1.26 1.17 0.32 7 8 9 10 11 12 3.05" 2.65 3.02 2.85 2.83 2.97 0.53" 1.13 0.71 1.33 1.17 0.40 15 16 17 3.11" 2.83 3.12 2.84 2.86 2.74 0.85" 1.31 1.06 0.50 1.43 1.29 19 20 21 22 23 24 3.41" 2.89 2.65 3.28 2.94 2.64 1.61" 1.09 1.08 0.46 1.58 0.97 18 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)
