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 1 2 3 4 5 6 3.35" 3.10 3.12 3.39 2.97 2.76 R 0.71" 1.13 1.43 1.21 1.22 0.37 Hour X Hour R X R Hour 3.01" 0.80" 19 7 3.05" 8 2.75 0.53" 13 1.18 14 2.93 1.26 20 9 3.02 0.71 15 3.02 1.01 21 10 2.95 1.28 16 2.74 0.45 22 11 2.73 1.12 17 2.76 1.43 23 12 2.97 0.35 18 2.74 1.29 24 4.51" 2.99 2.55 3.28 2.94 2.54 R 1.66" 1.14 1.08 0.41 1.63 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 (UCL) = 3.745 inches (round your response to three decimal places). Lower Control Limit (LCL) = inches (round your response to three decimal places).

ampling 4 pieces of precision-cut wire (to be used in computer assembly) every hour for the past 24 hours has roduced the following results: Sased on the sampling done, the control limits for 3-sigma x chart are (round all intermediate calculations to three lecimal places before proceeding with further calculations): Upper Control Limit (UCL)= inches (round your response to three decimal places). Lower Control Limit (LCLx)= inches (round your response to three decimal places)
