Refer to Table S6.1. 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 x 3.25" 3.20 3.22 3.39 2.97 2.76 R 0.65" 1.18 1.38 1.21 1.12 0.42 Hour X 7 3.15* 8 2.75 9 3.02 2.75 2.73 R 0.48" 1.18 0.76 1.28 1.12 Hour 13 14 15 16 17 18 X 3.21" 2.93 3.22 2.94 2.76 2.84 R Hour X 0.85 19 4.51 1.28 20 2.79 1.0121 2.65 0.45 22 3.18 143 23 2.94 1.24 2 4 2.64 R 1.56" 1.04 1.08 0.46 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)
