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 90 19 20 UWN 3.15" 3.20 3.22 3.49 3.17 2.96 R Hour 0.65" 7 1.23 8 1.389 1.21 10 1.22 11 0.37 12 3.15" 2.75 3.02 2.95 2.73 2.97 R 0.53" 1.18 0.76 1.33 1.22 0.45 Hour 133.21" 14 2.93 15 3.12 16 2.84 17 2.96 18 2.84 R 0.90" 1.26 1.01 0.45 1.48 1.34 Hour 3.31" 2.89 212.55 3.38 2.94 2.64 R 1.66" 1.09 1.03 0.51 1.53 1.02 22 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)
