Refer to Table S6.1-Factors for Computing Control

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 1 R Hour 3.35" 0.71" 7 3.20 1.13 8 1.66" 19 4.51 20 2.79 2 1.04 3 X R Hour 2.95" 0.48" 13 2.55 1.18 14 3.32 1.38 9 3.12 0.76 3.49 1.21 10 2.75 1.28 3.17 1.17 11 2.93 2.86 0.37 12 3.07 3.21 0.80 2.73 1.31 3.02 2.74 2.86 1.11 21 2.55 1.13 4 0.55 3.38 0.46 5 1.22 1.38 23 3.04 1.63 6 0.45 18 2.84 1.29 24 2.54 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): X Definition Sample Mean Factor, Size, n Upper Range, D Lower Range, D3 A 2 1.880 3.268 0 3 1.023 2.574 0 4 0.729 2.282 5 0.577 2.115 6 0.483 2.004 7 0.419 1.924 8 0.373 1.864 9 0.337 1.816 10 0.308 1.777 12 0.266 1.716 a) Set control limits for this process for the x-chart.
