Question 59

(0)

Which statement(s) are incorrect about Fractional Factorial Designs?

Question 60

(0)

Question 51

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?

Summary of the targeted critical metrics for process performance measurement

All of the above

Question 52

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

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

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

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

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

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

Question 53

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

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

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

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

These plots prove a statistically significance factor with 95% confidence

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.

256

Question 55

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

The Experimental Design is half-fractional

The Main Effects are confounded with only 4-way interactions

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

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

Question 56

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

It is unknown from this graph how many factors were in the Experimental Design

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

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

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

Question 59

Which statement(s) are incorrect about Fractional Factorial Designs?

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

Quarter Fractional experiments can exist for those with 4 factors

Resolution V design is desired while controlling costs of experimentation

Half Fractional experiments do not exist for those designs with only 2 factors
