PART 1 QUESTIONS 1-40

Question 1: Two events are mutually exclusive. P(A) = 0.25 and P(B) = 0.35. What is P(A or B)?

Choices:

1) 0.10

2) 0.90

3) 0.0875

4) 0.60

Correct Answer: 0.60

Explanation: For mutually exclusive events, P(A or B) = P(A) + P(B) because the intersection is zero. Thus 0.25 + 0.35 = 0.60.Page 1

Question 2: Which basic quality tool is best for displaying the shape, center, and spread of measured cycle-time data?

Choices:

1) Histogram 2) A�nity diagram 3) Pareto chart 4) Flowchart

Correct Answer: Histogram

Explanation: A histogram groups continuous numerical data into intervals and shows the distribution's shape, center, and spread.

Question 3: A customer audits a supplier to determine whether the supplier can

consistently meet contract requirements. What type of party audit is this?

Choices:

1) Self-assessment only 2) First-party audit 3) Third-party audit 4) Second-party audit

Correct Answer: Second-party audit

Explanation: A customer auditing its supplier is a second-party audit. First-party audits are internal audits, while third-party audits are performed by an independent external organization such as a certi�cation body.Page 2

Question 4: Which method is most appropriate when an organization wants detailed qualitative feedback from a small group of customers about why they prefer one service design over another?

Choices:

1) Acceptance sampling 2) Focus group 3) Control chart 4) Gage R&R study

Correct Answer: Focus group

Explanation: A focus group allows guided discussion with a small group and is useful for exploring reasons, perceptions, expectations, and reactions in depth.Question 5: A 95% con�dence interval for the di�erence in two process means is -0.8 to 2.4. At approximately the 0.05 signi�cance level, what is the best conclusion about a two-sided test of no di�erence?

Choices:

1) Conclude the �rst mean is de�nitely larger 2) Conclude both processes are identical in every respect 3) Fail to reject no di�erence because the interval includes zero 4) Reject no di�erence because the interval is wide Correct Answer: Fail to reject no di�erence because the interval includes zero Explanation: Because the 95% con�dence interval includes zero, a two-sided test at about α = 0.05 would not show a statistically signi�cant di�erence in the means.Page 3
