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 R Hour R X R 7 1 2 3 3.25" 3.10 3.12 3.39 2.97 2.86 0.71" 1.13 1.43 1.26 1.22 0.37 3.05" 2.65 3.12 2.75 2.93 2.87 8 9 10 11 12 0.53" 1.13 0.66 1.33 1.12 0.35 Hour 13 14 15 16 17 18 3.11" 2.73 3.12 2.94 2.76 2.84 0.85" 1.31 1.01 0.55 1.43 1.34 Hour 19 20 21 22 23 24 x 3.31" 2.89 2.65 3.38 2.94 2.54 R 1.61" 1.04 1.08 0.41 1.53 0.92 4 5 6 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).
