ASQ ASQ-CQE Online Questions & Answers

• Question 221:

  A test-retest study is performed to a coordinate measuring machine (CMM) using a working standard of 100.00 ?0.001 mm (95% confidence). The length of the standard is measured 30 rimes. The mean and standard deviation of the measurements are x = 107.88: mm and 5 = 2.497 mm. All of the measurements are made are the same location on the standard and are taken by the same technician, who mounts and dismounts the unit for each measurement.

  The necessary correction for the CMM is estimated to be ____

  A. -7.883 rum
  B. -2.497 mm
  C. 2.497 mm
  D. 7.883 mm
  A. -7.883 rum

  ---

  Explanation

  The correction for the CMM is determined by the difference between the measured mean and the standard value.

  The necessary correction is calculated as follows:Correction=Standard ValueMeasured Mean\text{Correction} = \text{Standard Value} - \text{Measured Mean}Correction=Standard ValueMeasured MeanCorrection=100.00107.88=7.88 mm\text {Correction} = 100.00 - 107.88 = -7.88 \text{ mm}Correction=100.00107.88=7.88 mm The correction should be applied in such a way to adjust the measurements to the standard value.

• Question 222:

  An engineer is part of a new product team and has found an issue with one of the product's parts. The part's supplier has documented that the part is known to follow a normal distribution, but it has a large variance when produced. The engineer's product design has accounted for variations and incorporated the pan. Which of the following design processes did the engineer follow?

  A. Design-to-cost
  B. Design for robustness
  C. Axiomatic design
  D. Design for test
  B. Design for robustness

  ---

  Explanation

  Design for robustness focuses on creating products that can perform consistently under a variety of conditions and account for variations in production. By considering the variance in the part's production, the engineer ensures that the product

  design is tolerant to such variations, thereby making the product more reliable and durable.

• Question 223:

  Which of the following quality system provisions is of the greatest concern when preparing an audit checklist for a vendor qualification system audit?

  A. Drawing and print control.
  B. Makeup of the MRB
  C. Training level of inspectors.
  D. Calibration of test equipment.
  D. Calibration of test equipment.

• Question 224:

  Given the data below is normally distributed, and the population standard deviation is 3.1, what is the 90% confidence interval for the mean?

  22, 23, 19, 17, 29, 25

  A. 20.88 - 24.12
  B. 20.42 - 24.59
  C. 21.65 - 23.35
  D. 17.4 - 27.6
  B. 20.42 - 24.59

  Explanation

• Question 225:

  Consider the following statement:

  "A defect which might affect the appearance or general function of essential parts" This definition describes a seriousness classification described as

  A. Incidental.
  B. Critical.
  C. Minor.
  D. Major.
  D. Major.

  Explanation

• Question 226:

  Which of the following statements is true about control charts?

  A. They are used to identify the root cause of process problems.
  B. They are used to identify which products to inspect.
  C. They enable production to use process improvements to reduce unit costs.
  D. They provide a common language for discussing process performance.
  D. They provide a common language for discussing process performance.

  ---

  Explanation

  Control charts are primarily used to monitor process behavior and provide a common language fordiscussing process performance. They help in identifying variation within a process and distinguishing between common cause and special cause variations. While they can suggest areas for further investigation, their primary role is not to identify root causes or decide which products to inspect.

• Question 227:

  The power of efficiency in designed experiments lies in the

  A. Random order of performance.
  B. The sequential and cyclical procedure of conjecture to design to analysis and back to conjecture.
  C. Hidden replication.
  D. The large number of possible combinations of factors.
  C. Hidden replication.

  Explanation

• Question 228:

  Given that the population standard deviation is 6.8, what sample size is required to be 90% confident that the estimated mean has an error less than 0.02?

  A. 312,761
  B. 189,859
  C. 175,987
  D. 152,083
  A. 312,761

  Explanation

• Question 229:

  The failure rate model above is used to show a typical relationship of many parts between their failure rate and the time in service. The reliability function for period "B" is BEST represented by

  

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

  Explanation

• Question 230:

  Which of the following elements of a quality system will help reduce errors and defects caused by conflicting work instructions?

  A. Product specifications
  B. Quality training
  C. Document control
  D. Cross-functional teams
  C. Document control

  ---

  Explanation

  Document control is a critical element of a quality system that ensures that all work instructions, procedures, and specifications are up-to-date, consistent, and accessible to relevant personnel.Proper document control helps prevent errors and

  defects caused by outdated or conflicting work instructions.
