Twenty 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 QuestionsDifferentiate between statistical process control and acceptance sampling. What is the purpose of each? Differentiate between the Process Potential Index (Cp) and the Process Capability Index (Cpk). In what way(s) are they similar? In what way(s) do they differ? The data in file XR20061 represent 30 samples, each with n = 3 items measured in inches. For the associated mean and range charts, have your statistical software apply all of the diagnostic tests of which it is capable. Has ...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 = 17.35 kilograms and s = 0.95 kilograms. The upper and lower ...Given the conclusion reached in the solution for Exercise 20.74, with the data in file XR20074, is it appropriate to compute the Process Capability Index (Cpk) for this process? If so, determine the overall mean and standard ...
