LLower Control Limit (LCL-x) = inches

B) Based on the x-chart the wire cutting process has been ( . )

C)

Upper Control Limit ( UCLr) = ( . ) inches (round your response to three decimal places)

Lower Control Limit ( LCLr) =

based on the R-chart, the wire cutting process has been

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 2 3.35" 3.20 3.22 3.39 2.97 2.96 R Hour 0.76" 1.238 1.43 1.21 10 1.12 11 0.37 12 2.95" 2.55 2.92 2.85 2.83 .97 R 0.58" 1.08 0.71 1.33 1.17 0.35 Hour x 133.01" 14 2.73 15 3.12 16 2.94 17 2.96 18 2.84 R 0.90" | 1.31 1.11 0.45 1.48 1.24 Hour X 19 3.41" 202.79 21 2.75 22 3 .28 23 3.04 24 2.74 R 1.61" 1.04 1.03 0.46 1.58 4 5 6 2 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). * Definition Upper Range, Lower Range, Sample Size, n D4 Mean Factor, A2 1.880 1.023 0.729 0.577 0.483 0.419 0.373 0.337 0.308 0.266 OOO 3.268 2.574 2.282 2.115 2.004 1.924 1.864 1.816 1.777 1.716 0.076 0.136 0.184 0.223 0.284
