The 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

Which 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 completion

Upon 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 above

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

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

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

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

Which statement(s) are correct about the Pareto Chart shown here for the DOE analysis? (Note:
There are 2 correct answers).
