ASQ ASQ-CQE Online Questions & Answers

• Question 81:

  A purchase order for subassemblies classified as critical must include a review by:

  I - Quality engineering.

  II - The procurement department.

  III - Design engineering.

  A. III only
  B. I and III only
  C. II and IIIonly
  D. I,II and III
  D. I,II and III

  Explanation

• Question 82:

  Regardless of the distribution of the individuals, the distribution of the average of n samples will follow which distribution as n becomes large?

  A. Normal
  B. Poisson.
  C. Exponential.
  D. Lognormal.
  A. Normal

  Explanation

• Question 83:

  Which of the following information should be contained in work instructions?

  A. Training requirements
  B. Production cost formulas
  C. Design review formulas
  D. Equipment needed to do the work
  D. Equipment needed to do the work

  ---

  Explanation

  Work instructions are detailed documents that provide step-by-step guidance on how to perform specific tasks. They should include all necessary information to ensure the task is completed correctly and efficiently. Work instructions should contain detailed procedures, including the equipment needed to perform the work. This ensures that employees have all the information required to complete their tasks properly.

• Question 84:

  Which of the following tools is effective for evaluating all possible causes of a problem and isolating the probable causes?

  A. Pareto chart
  B. Control chart
  C. Scatter diagram
  D. Fishbone diagram
  D. Fishbone diagram

  ---

  Explanation

  The fishbone diagram, also known as the Ishikawa or cause-and-effect diagram, is used to identify and evaluate all possible causes of a problem.

  It visually organizes potential causes into categories, helping to isolate the most probable ones.

  This tool is effective for brainstorming and systematically analyzing the root causes of a quality issue.

  References: ASQ's "Quality Toolbox" and Ishikawa's original works on cause-and-effect diagrams.

• Question 85:

  Information that is received by upper management, is often distorted. Which of the following actions is effective in countering this problem?

  I - Stop killing the messenger.

  II - Establishing an open door policy.

  III - Practice management by walking around.

  A. I only
  B. I and II only
  C. I andI II only
  D. I,II and III
  D. I,II and III

  Explanation

• Question 86:

  If the mean time between failures (MTBF) for a device is 200 hours, what is the constant failure rate per hour?

  A. 0.005
  B. 0.002
  C. 0.500
  D. 0.200
  B. 0.002

  ---

  Explanation

  The constant failure rate per hour is calculated as the inverse of the mean time between failures (MTBF). Given an MTBF of 200 hours: Failure rate () = 1 / MTBF = 1 / 200 = 0.005

• Question 87:

  Findings and observations are audit terms. The best relationship between these terms is which of the following?

  A. Observations are broader in scope than findings.
  B. Observations are seen; findings are discovered.
  C. Observations generally support findings.
  D. Findings are reported in writing, observations are reported verbally.
  C. Observations generally support findings.

  Explanation

• Question 88:

  A normal (Gaussian) distribution curve is

  A. Bell shaped.
  B. Dome shaped.
  C. Pear shaped.
  D. Positively skewed.
  A. Bell shaped.

  Explanation

• Question 89:

  Which of the following tools begins at the point of failure and works back through the process to the components?

  A. Fault tree analysis
  B. Pugh matrix
  C. Cause and effect matrix
  D. Kappa analysis
  A. Fault tree analysis

  ---

  Explanation

  Fault tree analysis (FTA) is a tool that begins at the point of failure and works back through the process to the components. FTA is used to identify the root causes of system failures by constructing a logical diagram of the various possible causes. This method helps in understanding the paths leading to a failure and identifying corrective actions.

  "Reliability, Maintainability, and Risk" by David J. Smith, which describes fault tree analysis and its application in failure analysis.

• Question 90:

  The primary focus of design FMEA (DFMEA) is to

  A. identify personnel responsible for implementation
  B. predict failure frequencies
  C. minimize measurement variation
  D. mitigate failure modes
  D. mitigate failure modes

  ---

  Explanation

  Design Failure Mode and Effects Analysis (DFMEA) is a systematic method for evaluating a design to identify potential failure modes, their causes, and effects, and to prioritize the actions to mitigate these failures.

  Identify Personnel Responsible for Implementation:

  While important for action plans, it is not the primary focus of DFMEA.

  Predict Failure Frequencies:

  DFMEA does consider failure frequencies, but the primary goal is to address and mitigate failures.

  Minimize Measurement Variation:

  This is more relevant to process control and not the primary focus of DFMEA.

  Mitigate Failure Modes:

  The main objective of DFMEA is to identify potential failure modes and implement actions to reduce or eliminate the risks associated with these failures. This involves analyzing the design to foresee where it might fail and taking preventive

  measures to improve reliability and safety.
