Question: Lower Control Limit (LCL Subscript x overbarLCLx) = ? Based on the x overbarx-chart, the wire cutting process has been IN CONTROL or OUT OF
Lower Control Limit (LCL Subscript x overbarLCLx) = ? Based on the x overbarx-chart, the wire cutting process has been IN CONTROL or OUT OF CONTROL?
The control limits for the 3-sigma R-chart are (round all intermediate calculations to three decimal places before proceeding with further calculations): Upper Control Limit (UCL Subscript Upper RUCLR) = ? Lower Control Limit (LCL Subscript Upper RLCLR) = ? Based on the R-chart, the wire cutting process has been IN CONTROL or OUT OF 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 x R Hour R Hour R 1 2 13 14 3 4 3.15" 3.10 3.22 3.29 3.07 2.96 R 0.76" 1.23 1.48 1.26 1.22 0.37 Hour 7 8 9 10 11 12 x 2.95" 2.75 3.02 2.95 2.83 2.97 0.58" " 1.13 0.71 1.38 1.22 0.40 15 16 17 18 X 3.11" 2.83 3.02 2.94 2.96 2.84 0.90 1.36 1.06 0.45 1.43 1.24 19 20 21 22 23 X 3.41" 2.89 2.55 3.28 2.94 2.64 1.56" 1.09 1.13 0.51 1.53 0.97 5 6 24 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). i Definition Sample Size, n 2 3 4 5 Mean Factor, A2 1.880 1.023 0.729 0.577 0.483 0.419 0.373 0.337 0.308 0.266 Upper Range, D4 3.268 2.574 2.282 2.115 2.004 1.924 1.864 1.816 1.777 1.716 Lower Range, D3 0 0 0 0 0 0.076 0.136 0.184 0.223 0.284 6 7 8 9 10 12Step by Step Solution
