Twelve samples have been taken from a production run. Given the following data, construct a 3-sigma p-chart and evaluate whether the process is in control.
Answer to relevant QuestionsTwenty samples have been taken from a production run. Given the following data, construct a 3-sigma p-chart and evaluate whether the process is in control. Using the control limits determined in Exercise 20.52, evaluate whether the process was in control when the following data were collected for vehicles 21–30. Repeat Exercise 20.52 and apply all of the diagnostic tests available with your statistical software. Has applying these diagnostics to the c-chart raised any concerns regarding the state of control of the process? If so, in ...A process is in control and the results from a series of samples show the overall mean and standard deviation of all the units sampled to be x-double bar = 21.4500 inches and s = 0.0969 inches. The upper and lower ...Given the conclusion reached in the solution for Exercise 20.75, with the data in file XR20075, is it appropriate to compute the Process Capability Index (Cpk) for this process? If so, determine the overall mean and standard ...
