N = 5, p = 0.01, x = 5 Apply Standard formula for Binomial Distribution. Thus, option b is the
correct answer.

the first four phases of DMAIC?
, IASSC LSSGB EXAM Questions With
Solutions 100% Correct
A. The green belt alone; the project has been successfully completed.

team?
A. Increase Sample Size
B. Reduce Sample Size
C. Reduce Significance level
, IASSC LSSGB EXAM Questions With
Solutions 100% Correct
D. All of the above A. Increase Sample Size

increase in sample size increases the possible accuracy of the experiment, and thus an increase in
power. So, option a is the correct answer.
Hypothesis testing is usually done to:
A. Statistically validate if a sample mean belongs to the population
B. Statistically validate if means of two groups are the same or if they are significantly different
C. Statistically validate if variances of two groups are the same or if they are different.
D. All of the above D. All of the above

Solutions 100% Correct
Statistically validate if a sample mean does belong to the population, find if means of two groups
are the same or if they are significantly different, and validate if variances of two groups are the
same or if they are different. Option d is the correct answer.
What is the concept behind PDCA?
A. The Deming/Shewhart cycle
B. Process flow
C. Continuous improvement
D. Satisfying suppliers C. Continuous Improvement
