100% Real & Accurate CQE Questions and Answers with Free and Fast Updates

ASQ CQE (Certified Quality Engineer) Certification Exam is a globally recognized certification that validates the knowledge and skills of a quality engineer. It is designed to assess the proficiency of candidates in various aspects of quality engineering, such as quality tools and techniques, statistical process control, and Six Sigma methodologies. The CQE certification serves as a testament to an individual’s mastery of quality engineering principles and their ability to apply them effectively in their organization.

The CQE certification exam is a comprehensive exam that requires candidates to demonstrate their knowledge and skills in a wide range of quality engineering topics. CQE exam consists of 175 multiple-choice questions that are designed to test the candidate’s understanding of quality engineering concepts and principles. CQE exam is four hours long and is administered at Prometric testing centers around the world.

NO.98 Rank in order, from most to least effective, the controls for mitigating risk.
1. Safety devices
2. Design change
3. Training

1,2,3

1,3,2

2,1,3

2,3,1

The most effective controls for mitigating risk are generally ranked as follows: 2. Design change: It is the most effective as it eliminates hazards at the source by redesigning the product or process.
* Safety devices: These provide protection by incorporating safety mechanisms into the design but are secondary to eliminating the hazard.
* Training: It is the least effective as it relies on human behavior and adherence to procedures.

NO.99 A pre-award evaluation of a supplier’s quality system capability should NOT include consideration of

The supplier’s product-quality history.

The supplier’s geographical location.

The supplier’s implementation of quality manual procedures.

The supplier’s skills in quality control techniques.

NO.100 A leak test is performed on every water tank. The production superintendent wants to know the location of each leak on defective tanks. Which of the following tools is most appropriate for collecting this data?

Pareto diagram

Automatic gauging system

Data coding

Check sheet

To collect data on the location of each leak on defective tanks, the most appropriate tool is a check sheet. A check sheet allows for the systematic recording and compiling of data, making it easy to identify and locate defects.Reason: A check sheet is used to collect data in a structured manner and is particularly useful for tracking the frequency and location of defects.

NO.101 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

Option A

Option B

Option C

Option D

NO.102 What is the appropriate number of class intervals for the construction of a histogram generated from 36 observations?

The appropriate number of class intervals for the construction of a histogram can be estimated using Sturges’ rule, which is given by k=1+3.322log10(n)k = 1 + 3.322 \log_{10}(n)k=1+3.322log10(n), where nnn is the number of observations. For 36 observations:
k=1+3.322log10(36)1+3.322×1.5566.17k = 1 + 3.322 \log_{10}(36) \approx 1 + 3.322 \times 1.556 \approx
6.17k=1+3.322log10(36)1+3.322×1.5566.17
This suggests around 6 intervals, but in practice, the number of intervals often rounded up, hence the appropriate number of class intervals would be 8 for better representation of the data. References:

NO.103 Which of the following tools can be used to show a frequency distribution?

An affinity diagram

An interrelationship digraph

A PERT chart

A check sheet

A check sheet is a structured, prepared form for collecting and analyzing data.
It is one of the seven basic quality tools used to record frequency of events or defects, making it ideal for showing frequency distribution.
Affinity diagrams and interrelationship digraphs are used for organizing ideas and identifying relationships, while a PERT chart is used for project scheduling.
References: The ASQ and various quality management textbooks, such as “The Quality Toolbox” by Nancy R.
Tague, outline the use of check sheets for frequency distribution analysis.

NO.104 Which of the following definitions describes severity?

Probability that the failure would be avoided or detected

Probability that the failure will occur

Effect on uncertainty on objectives

Impact that the failure would have

Severity in the context of software quality and risk management refers to the extent of impact a failure would have on a system or process.
It assesses the consequences of a failure, regardless of its likelihood or detectability.
High severity indicates significant detrimental effects, such as critical system failures or safety hazards.
References: The ASQ and FMEA (Failure Mode and Effects Analysis) methodology define severity as the measure of the seriousness of the effect of a failure mode.

NO.105 Which of the following tools can be used to classify or determine a safety quality characteristic?

An inspection plan

A criticality analysis

Standard work instructions

A control chan

A criticality analysis is used to classify or determine the safety and quality characteristics of a product or process. This analysis evaluates the severity, occurrence, and detection of potential failures, helping to prioritize issues that could significantly impact safety and quality.

NO.106 Maintainability is

The probability of a system being restored to functional operation within a given period of time.

Performing adequate maintenance on a system.

Probability of survival of a system for a given period of time.

Maintaining a machine in satisfactory working condition.

NO.107 During the building phase of improvement team development, which of the following properly describes team activities?
I. The team leader is usually directive.
II. The team leader often delegates tasks.
III. Team members prioritize and perform duties.
IV. Team members are uncertain of their duties.

II and III only

I, II and III only

I and IV only

II, III and IV only

NO.108 The steeper the OC-curve, the

Less protection for both producer and consumer.

More protection for both producer and consumer.

The lower the AQL.

The smaller the sample size.

NO.109 Which table should be used to determine a confidence interval on the mean when standard deviation is NOT known and the sample size is 10?

Chi-Square

NO.110 If the probability of two cars starting on a cold morning is 0.6 for each car. what is the probability of at least one of the cars starting?

0.16

0.24

0.36

0.84

To find the probability of at least one car starting on a cold morning, we can use the complement rule.
* Determine the probability of one car not starting:
* Probability of a car starting: P(start)=0.6P(\text{start}) = 0.6P(start)=0.6
* Probability of a car not starting: P(not start)=10.6=0.4P(\text{not start}) = 1 – 0.6 =
0.4P(not start)=10.6=0.4
* Determine the probability of neither car starting:
* Since the cars are independent, the probability of both cars not starting is:
P(both not start)=0.4×0.4=0.16P(\text{both not start}) = 0.4 \times 0.4 =
0.16P(both not start)=0.4×0.4=0.16
* Determine the probability of at least one car starting:
* P(at least one starts)=1P(both not start)=10.16=0.84P(\text{at least one starts}) = 1 – P(\text{both not start}) = 1 – 0.16 = 0.84P(at least one starts)=1P(both not start)=10.16=0.84 References: Basic principles of probability and complement rule from standard probability texts.

NO.111 A “p” chart

Can be used for only one type of defect per chart.

Plots the number of defects in a sample.

Plots either the fraction or percent defective in order of time.

Plots variations in dimensions.

NO.112 One-way analysis of variance is MOST similar in its objectives to

A test of a population mean.

A test for equality of two sample proportions.

A test for equality of two population means.

A chi-square test for independence.

NO.113 The pre-production or pre-service planning process should include which of the following activities?

Preparation of product and process control plans

Implementation of process quality audits

Development of cost of quality parameters

Certification of suppliers

The pre-production or pre-service planning process should include the preparation of product and process control plans. These plans outline the necessary steps and controls to ensure that the product meets quality requirements and that the process is capable of producing consistent results.References:
