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: R Hour Hour x R 7 8 Hour 1 2 3 4 5 6 WN 3.25" 3.10 3.22 3.29 3.17 2.76 0.65" 1.23 1.38 1.31 1.17 0.42 9 10 11 12 3.05" 2.65 3.02 2.95 2.73 3.07 R 0.48" 1.18 0.66 1.33 1.17 0.45 13 14 15 16 17 18 3.21" 2.73 3.22 2.84 2.86 2.64 0.90" 1.31 1.11 0.45 1.48 Hour 19 20 21 22 23 24 3.41" 2.99 2.75 3.38 2.94 2.54 R 1.56" 1.09 1.03 0.41 1.58 0.92 1.29 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).
