Consider the following questions, and then write a brief report to Michelle summarizing your findings.
Question 1: How did Jim conclude that the process was not capable based on his first set of samples? (Hint Estimate the process standard deviation, a, using A2R ≈ 3 σ/√n). )
Question 2: Does the second set of samples show anything that the first set didn't? Explain what and why.
Question 3: Assuming the problem can be found and corrected, what impact do you think this would have on the capability of the process? Compute the potential process capability using the second data set
Question 4: If small samples can reveal something that large samples might not, why not just take small samples in every situation?
