CO Homework: Portfolio 2 Part 2 (chapter 6 & supplement 6) Question 4, Problem 6s.6 Part 4 of 6 HW Score: 7.87%, 3.93 of 50 points O Points: 0 of 3 Save 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 Hour R Hour R X 4.51" 2.89 2.65 1 2 3 4 5 6 3.35 3.00 3.32 3.29 3.07 2.96 0.76" 1.18 1.38 1.31 1.17 0.32 X 3.15 2.55 3.02 2.95 2.73 7 8 9 10 11 12 0.58" 1.13 0.66 1.33 1.17 0.40 13 14 15 16 17 18 3.11 2.83 3.02 2.74 2.86 2.84 0.80" 1.26 1.11 0.50 1.38 1.29 19 20 21 22 23 24 1.61 1.09 1.08 0.41 1.63 3.38 s 3.04 2.64 3.07 0.97 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;) = 3.785 inches (round your response to three decimal places). Lower Control Limit (LCL;) = 2.295 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)
