QUESTION 10Following the completion of a LSS project the Belt not only creates a Control Plan he also develops a
_____________ so those involved in the process know what to do when the critical metrics move out of
spec.
A. Response Plan
B. Call List
C. Chain-of-Command
D. Defect Analysis PlanCorrect Answer: A 
QUESTION 11The Control Limits width varies if the sample size varies for which type of chart?
A. P Charts
B. NP Charts
C. Xbar-R Charts
D. Time Series Charts

Correct Answer: A 
QUESTION 12Which of these elements are not included in Implementation plans?
A. Work breakdown structure
B. Risk management plans
C. Cost/Benefit ratios
D. Planned audits of work completionCorrect Answer: C 
QUESTION 13Upon completion and validation of an improvement to a process a Belt and the Project Team create a
Control Plan that contains which of these?
A. Standard operating work description of the process change
B. Description of the monitoring system in place to assure continued compliance
C. Summary of the targeted critical metrics for process performance measurement
D. All of the aboveCorrect Answer: D
 QUESTION 14What 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 outputCorrect Answer: D 
QUESTION 15Which 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 16
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 17
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 18
Which statement(s) are correct about the Pareto Chart shown here for the DOE analysis? (Note: There are
2 correct answers).

 A. It is unknown from this graph how many factors were in the Experimental Design
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. The factors to keep in the mathematical model with a 5% alpha risk are BE, AB, A and ADCorrect Answer: AC 

QUESTION 19Fractional Factorial, ____________and Response Surface Method are types of planned experiments.
A. Multi-Vari Analysis
B. Baldridge Channels
C. One Factor at a Time or OFAT
D. Factorial DesignCorrect Answer: D

 QUESTION 20Relative to a Design of Experiments the term ________________ refers to variables being a linear
combination of each other.
A. Mirror Image
B. Directly Parallel
C. Collinear
D. None of the aboveCorrect Answer: C 

QUESTION 21Which statement(s) are incorrect about Fractional Factorial Designs?
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 experimentationD. Half Fractional experiments do not exist for those designs with only 2 factorsCorrect Answer: C

 QUESTION 22If in an experiment all possible variable pairs sum to zero the design is Orthogonal.
A. True
B. FalseCorrect Answer: A
