  A. Poke-Yoke

  B. Standard Operating Procedures

  C. Kaizen

  D. 5S the work area

  Correct Answer: B

• Question 95:

  When conducting a Hypothesis Test using Continuous Data the proper sample size is influenced by the extent to which we need to assess a Difference to be detected and the inherent variation in the process.

  A. True

  B. False

  Correct Answer: A

• Question 96:

  The validity of the decision made with Hypothesis Testing is dependent upon all of these except ___________________.

  A. Beta risk

  B. Alpha risk

  C. Range of data

  D. Sample size

  Correct Answer: C

• Question 97:

  Statistical Difference is the magnitude of difference or change required to distinguish between a true difference, brought about by change or improvement, and one that could have occurred by chance.

  A. True

  B. False

  Correct Answer: A

• Question 98:

  A(n) ________________ has occurred when two inputs have a greater impact on a change in the output than either of the inputs has by itself.

  A. Dependency

  B. Bimodal reaction

  C. Interaction

  D. Amplified effect

  Correct Answer: C

• Question 99:

  What conclusion is most correct about the Experimental Design shown here with the response in the far right column?

  

  A. No factor has enough statistical confidence greater than 95% to have an impact on the response rate

  B. Constant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more

  C. If the Adv is increased from the low level to the high level, the response rate increases

  D. The response level is statistically concluded to only need the Adv and Bev factors set at the low level to get the largest response rate

  E. This design does not have enough experimental runs to conclude anything as evidenced by the lack of P-values in the MINITABTM output

  Correct Answer: D
