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 x R 1 2 3 x 3.15" 3.20 3.12 3.49 3.07 2.96 0.76" 1.23 1.48 1.21 1.17 0.42 Hour 7 8 9 9 10 11 12 x R 3.05" 0.53" 2.75 1.08 3.02 0.66 2.95 1.33 2.93 1.17 3.07 0.40 13 14 15 16 17 x 3.01" 2.73 3.02 2.74 2.96 2.84 0.85" 1.26 1.11 0.50 1.38 1.24 19 20 21 22 23 24 4.51" 2.89 2.55 3.38 3.04 2.74 1.66" 1.04 1.13 0.41 1.58 0.92 4 5 6 18 Based on the sampling done, the control limits for 3-sigmax 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).
