Consider the velocity of light data introduced in Exercises 6.69 and 6.70. Use only the 20 observations in Exercise 6.69 to set up a CUSUM with target value 734.5. Plot all 40 observations from both Exercises 6.69 and 6.70 on this CUSUM. What conclusions can you draw?
Answer to relevant QuestionsRework Exercise 9.23 using an EWMA with = 0.10. = 0.1; L = 2.7; CL = 0 = 734.5; = 108.7 Reconsider the data in Exercise 9.7. Apply an EWMA control chart to these data using = 0.1 and L = 2.7. 12.16 , CL = 0 = 950, UCL = 957.53, LCL = 942.47. Analyze the data in Exercise 9.4 using a moving average control chart with w = 5. Compare the results obtained with the cumulative sum control chart in Exercise 9.4. w = 5, 0 = 8.02, = 0.05, CL = 8.02, UCL = 8.087, ...A Shewhart x chart has center line at 10 with UCL = 16 and LCL = 4.
