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 Hour 1 13 2 3 4 5 6 3.15" 3.10 3.22 3.49 3.07 2.76 R 0.65" 1.23 1.38 1.31 1.12 0.32 7 8 9 10 11 12 3.15" 0.58" 2.55 1.18 3.02 0.66 2.75 1.28 2.83 1.22 3.07 0.45 14 15 16 17 18 R 3.01" 0.90" 2.93 1.31 3.12 1.11 2.74 0.50 2.96 1.43 2.64 1.29 19 20 21 22 23 24 X x 3.31" 2.99 2.75 3.18 2.84 2.74 R 1.56" 1.09 1.13 0.51 1.58 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)
