  B. The factors to keep in the mathematical model are E, D, DE, BD and B with an alpha risk equal to 2.06

  C. The effects to keep in the mathematical model are E, D, DE, BD and B with an alpha risk equal to 0.05

  D. Both a and c

  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 324:

  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 325:

  Which statement(s) are correct about the Factorial Plot shown here?

  

  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. All of the above

  Correct Answer: D

• Question 326:

  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
