  A. A Half Fractional Design for 5 factors has the same number of experimental runs as a Full Factorial Design for 4 factors assuming no repeats or replicates or Center Points

  B. Quarter Fractional experiments can exist for those with 4 factors

  C. Resolution V design is desired while controlling costs of experimentation

  D. Half Fractional experiments do not exist for those designs with only 2 factors

  A. Linear combination

  B. Directly parallel

  C. Mirror image

  D. None of the above

  What is the Ppk of a process with a spread of 24 units, an average of 68, an upper limit of 82 and a lower limit of 54?

  A. 1.68

  B. 2.00

• Question 198:

  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.

  E. The maximum DPU in one observation was nearly 0.0753.

  Correct Answer: BCE

  D. Cp is better for the long-term

  Correct Answer: A

• Question 200:

  A. True

  B. False

  Correct Answer: A
