Based On The Sampling Done The Control Limits For 3 Sigmax Chart Are Round All Intermediate Calculations To Three Deci 2 (24.37 KiB) Viewed 75 times
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;)= 3.702 inches (round your response to three decimal places). Lower Control Limit (LCL;)= 2.204 inches (round your response to three decimal places). Based on the x-chart, the wire cutting process has been IN CONTROL The control limits for the 3-sigma R-chart are (round all intermediate calculations to three decimal places before proceeding with further calculations): 2.346 inches (round your response to three decimal places). Upper Control Limit (UCL) Lower Control Limit (LCLR)= 0.000 inches (round your response to three decimal places)
Refer to Table 56.1-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 1234 10 10 5 6 3.15 3.10 3.22 3.29 2.97 2.76 R 0.65* 1.18 1.43 1.21 1.22 0.32 X Hour R Hour X R Hour 7 2.95 0.58" 13 3.01 0.80 19 8 2.75 1.08 14 2.73 1.26 20 15 3.22 1.06 21 16 2.84 0.55 22 17 2.86 1.38 0.45 18 2.84 1.34 9 3.02 0.66 10 2.85 1.28 11 2.93 1.17 23 24 12 3.07 x 4.51" 2.99 2.55 3.18 2.84 2.74 R 1.61" 1.14 1.03 0.51 1.53 0.97
