• Question 61:

  Which statements are correct about the advanced Capability Analysis shown here? (Note: There are 3 correct answers).

  

  A. This is a Poisson Capability Analysis.

  B. The average DPU with 95% confidence is between 0.024 and 0.0295.

  C. The DPU does not seem to vary depending on sample size.

  D. The process shows only one instance of being out of control statistically so we have confidence in the estimated DPU of this process.
