Module 1 - Quality Management EXAM 2024
If the chance that any of five telephone lines is busy at any instant is 0.01,
then what is the probability that all the lines are busy? - answer-(0.01)^5

Who should complete the control phase after the successful completion and
implementation of the first four phases of DMAIC? - answer-The complete
team is the most desirable option.

To increase the power of experiments, what is the best option in the hands of
the Six Sigma team? - answer-Increase sample size

Which of the techniques used in DOE helps you in eliminating errors due to
nuisance factors? - answer-Blocking

Hypothesis testing is usually done to: - answer-1) Statistically validate if the
sample mean belongs to the population, 2) statistically validate if means of
two groups are the same or if they are significantly different, and 3)
statistically validate if variances of two groups are the same or if they are
different.

What is the concept behind PDCA? - answer-Continuous improvement

What are the experiments called while performing one experiment with five
repetitions? - answer-Replications

Which type of chart is used for small shifts in variation? - answer-CUSUM

What are the distinct types of variation that are displayed in control charts? -
answer-Chance (common or random) and assignable (special)

Which of the following is an advantage of the production of a product in large
lots? - answer-Machine efficiencies

A sample is to a statistic as a population value is to a: - answer-Parameter

A calculation for reproducibility results in a value of 0 (zero), while
repeatability yields a positive number. Without any other considerations,
what conclusion can be made regarding the reproducibility result? - answer-A
reproducibility of zero means there is no operator effect on this
measurement.

The average number of major storms in a city is 2 per year. What is the
probability that exactly 3 storms will hit next year? - answer-0.180 or 18%

Why are scatter diagrams useful in problem-solving? - answer-They show
relationships between variables.

The advantage of using the modern designed method of experimentation,
rather than the classical OFAT, is that: - answer-Fewer terms and
measurements are needed for valid and useful information.

What does ANOVA stand for? - answer-Analysis of variance

Which quality tool would not be expected to be used during the results
confirmation stage of a problem solution? - answer-Flow chart

Use a process flow chart in the Define and Measure stage.

If 6 consecutive samples were taken from a process and precisely measured,
you can still expect differences. What type of variation would be the most
difficult one to determine? - answer-Lot-to-lot variation

Which of the following inference tests does NOT require the knowledge of a
test or population variance? - answer-Chi-square test

Which of the following is the LEAST likely candidate to assist in the problem
definition stage of Six Sigma? - answer-Control charts

Control charts are used in the Measure and Control phases. Remember: The
process must first be brought into statistical control by detecting and acting
upon special causes of variation. Then its performance is predictable, and its
capability to meet customer expectations can be assessed (Cp and Cpk),
which is done in the Measure phase.

What is the name of the condition if you are running a 7x4 fractional
experiment, and you know factors A, B, C, D, and E are independent of each
other, but you suspect factors F and G are not independent. You conducted a
small sub-experiment and discovered a high correlation between factors F
and G. - answer-Collinearity

If P(A) is 0.6 and P(B) is 0.5 and the probability of either event happening is
0.85, what is the probability of both the events occurring? - answer-0.25
(additive rule)
