Question: I need upper and lower control R Refer to Table 56.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. Sampling 4

I need upper and lower control R Refer to Table I need upper and lower control R

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 R Hour R Hour R Hour R 1 7 19 8 2 3 9 3.35" 3.10 3.32 3.49 3.07 2.86 0.65" 1.18 1.38 1.26 1.22 0.37 3.05" 2.65 3.02 2.85 2.73 3.07 0.53" 1.13 0.66 1.28 1.22 0.45 13 14 15 16 17 3.21" 2.73 3.02 2.94 2.86 0.80" 1.26 1.06 0.45 1.48 1.34 4.51" 2.99 2.55 3.28 2.94 2.64 1.66" 1.14 1.13 0.41 1.53 1.02 20 21 22 23 24 4 10 11 12 5 6 18 2.84 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;) = 3.792 inches (round your response to three decimal places). Lower Control Limit (LCL2) = 2.298 inches (round your response to three decimal places). Based on the x-chart, the wire cutting process has been 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 (UCLR) = inches (round your response to three decimal places)
