  D. The factors to keep in the mathematical model with a 5% alpha risk are BE, AB, A and AD

  Correct Answer: AC

• Question 146:

  If an experiment has 5 factors and no replicates for a 2-level Experimental Design with 16 experimental runs which statement is incorrect?

  A. The Experimental Design is half-fractional

  B. The Main Effects are confounded with only 4-way interactions

  C. The Main Effects for the 5 factors are not aliased or confounded but the 2-way interactions are confounded with the 3-way interactions

  D. The experiment has 8 experimental runs with the first factor at the high level

  Correct Answer: C

• Question 147:

  How many experimental runs exist in a Full Factorial and fully randomized design for 4 factors with 2 replicates for the Corner Points and no Center Points? The factors in the experiment are only at 2-levels.

  A. 10

  B. 32

  C. 256

  D. 64

  Correct Answer: B

• Question 148:

  Which statement(s) are correct about the Factorial Plot shown here? (Note: There are 3 correct answers).

  

  A. When the cutting speed increased from low to high level, the tool age increases

  B. The coefficient of the metal hardness is positively related to the output of tool age

  C. The coded coefficient is lower for cutting speed than the cutting angle related to the output of tool age

  D. These plots prove a statistically significance factor with 95% confidence

  E. These plots are an example of interaction plots

  Correct Answer: ABC

• Question 149:

  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
