4. In the 6 Sigma approach, facing a point cloud like this, what should we do ?

Nothing

Eliminate defects by refocusing our process

Reduce the dispersion of our processes

Increase our acceptance tolerances

5. If I have non-normal data but want to use a tool that requires normality, what can I do?

Investigate non-normality

SMED

Using the Box Cox Transform

Only 4 out of 35 defect samples still have a defect in the second test.

Only 1 of the 36 defect samples always have a defect in the second test.

8.

What should we get at the end of each stage of DMAIC ?

Congratulations

none of these answers

The cause of the problem

The Go / No GO

9. Which of these proposals are necessary for a correct capability study ?

Data is normal

The power must be more than 0.8

The measuring system must be reliable

Data is biased

10. What differs in the calculation between DPMOs and PPMs ?

PPMs are based on the number of opportunity defects

DPMOs are based on the number of rejects

PPMs are not a default indicator

DPMOs are based on the number of opportunity defects

11. We performed a Fischer Snedecor test to evaluate the performance of our SMED project (we wanted to reduce the variability). We obtain the following result. What can we conclude?

Our results are very positive we have reduced the variability of the series changes

Our project had no effect, the variability is the same as before

We can not conclude anything because the Fisher Snedecor test is not adapted to the situation

Our project had a negative effect, the variability is even greater

12. What is the purpose of the Improve phase ?

Choose solutions

Test solutions

Identify solutions

13. I want to study whether there is a correlation between seat belt use and the severity of injuries. What tools will I use?

Qualitative nominal

Qualitative ordinal

Quantitative ratio

18. If we give Y = f (x1, x2, ... xn), does that mean?

The output Y is driven by a series of variables X1, ...

19. With inferential statistics, what will I be able to study?

Compare 3 averages of 3 groups of data

Estimate an average of a population

Estimate a proportion

Identify a correlation between 7 groups of data
