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 R Hour R Hour R Hour R 1 3.25" 0.65" 7 3.05" 0.58" 13 3.21" 0.80" 19 4.51" 1.66" 2 3.10 1.18 8 2.75 1.13 14 2.93 1.26 20 2.89 1.09 3 3.22 1.43 9 3.12 0.66 15 3.22 1.06 21 2.75 1.08 4 3.29 1.21 10 2.85 1.33 16 2.94 0.50 22 3.18 0.46 5 3.07 1.22 11 2.73 1.17 17 2.96 1.48 23 2.94 1.58 6 2.76 0.32 12 2.87 0.35 18 2.64 1.34 24 2.64 0.92 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 (UCLZ) = inches (round your response to three decimal places)
