NEW QUESTION # 69
Given a sample mean. X = 515. a sample standard deviation, s = 9. and a sample size, n = 6. what is the absolute value of the Student's t statistic to test if the sample mean is equal to the population mean, U = 500?
- A. 1.67
- B. 10.00
- C. 4.08
- D. 3.73
Answer: D
Explanation:
The Student's t statistic is calculated as follows:
t = (X - ) / (s / n)
Given:
* Sample mean (X) = 515
* Population mean () = 500
* Sample standard deviation (s) = 9
* Sample size (n) = 6
t = (515 - 500) / (9 / 6) = 15 / (9 / 2.45) 3.73

- A. batch control
- B. change control
- C. procedure control
- D. work instruction control

Change control is a systematic approach to managing changes to a product or system. This includes capturing product revisions to ensure that changes are introduced in a controlled and coordinated manner. This process helps maintain the integrity of the product and ensures traceability of changes.
NEW QUESTION # 75
When nonconforming items are found, which of the following actions should be taken first?
- A. A Retest
- B. Destruction
- C. Identification
- D. Return to supplier
Answer: C
Explanation:
When nonconforming items are found, the first action should be to identify and label them clearly. This prevents further processing or use and ensures proper handling of these items. Identification is critical before taking any further actions such as retesting, destruction, or returning to the supplier. Reference: ISO
9001:2015, Clause 8.7 - Control of Nonconforming Outputs, which specifies the need for clear identification and segregation of nonconforming products.

Which of the following tools begins at the point of failure and works back through the process to the components?
- A. Kappa analysis
- B. Cause and effect matrix
- C. Fault tree analysis
- D. Pugh matrix
Answer: C
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. Reference: "Reliability, Maintainability, and Risk" by David J. Smith, which describes fault tree analysis and its application in failure analysis.

NEW QUESTION # 83
A failure node and effects analysis (FMEA) should be classified in what cost of quality category?
- A. Appraisal
- B. Control
- C. Inspection
- D. Prevention
Answer: D
Explanation:
Failure Mode and Effects Analysis (FMEA) is a preventive action methodology used to identify and mitigate potential failures before they occur.
* Appraisal:
* Involves measuring and evaluating products to ensure they meet quality standards (e.g., inspection and testing).
* Prevention:
* Involves activities designed to prevent defects from occurring.
* FMEA falls under prevention as it proactively identifies potential failure modes and implements measures to mitigate them.
* Control:
* Involves monitoring processes to maintain quality, but does not directly relate to preventive analysis like FMEA.
* Inspection:
* Involves examining products or components to ensure they meet specifications, not preventive by nature.

The following components (1,2,3) each have reliabilities of 0.95.
What is the system reliability?
- A. 0.925
- B. 0.857
- C. 0.948
- D. 0.903
Answer: D
Explanation:
Given that components 1, 2, and 3 each have reliabilities of 0.95, and assuming the system configuration as depicted in the image (series-parallel configuration):
* Reliability of the parallel components (2 and 3): Rparallel=1[(1R2)×(1R3)]R_{\text{parallel}} = 1 - [(1
- R_2) \times (1 - R_3)]Rparallel=1[(1R2)×(1R3)] Rparallel=1[(10.95)×(10.95)]R_{\text{parallel}} = 1
- [(1 - 0.95) \times (1 - 0.95)]Rparallel=1[(10.95)×(10.95)] Rparallel=1[0.05×0.05]R_{\text{parallel}} =
1 - [0.05 \times 0.05]Rparallel=1[0.05×0.05] Rparallel=10.0025R_{\text{parallel}} = 1 -
0.0025Rparallel=10.0025 Rparallel=0.9975R_{\text{parallel}} = 0.9975Rparallel=0.9975
* Reliability of the entire system (series of component 1 and the parallel system):
Rsystem=R1×RparallelR_{\text{system}} = R_1 \times R_{\text{parallel}}Rsystem=R1×Rparallel Rsystem=0.95×0.9975R_{\text{system}} = 0.95 \times 0.9975Rsystem=0.95×0.9975 Rsystem=0.947625R_{\text{system}} = 0.947625Rsystem=0.947625 Rounded to three decimal places, the system reliability is 0.948.

NEW QUESTION # 89
The most desirable outcome of a design FMEA (DFMEA) is
- A. a reduction in design risk
- B. a severity classification matrix I
- C. an estimate of failure frequency
- D. a comprehensive list of design functions
Answer: A
Explanation:
Design Failure Mode and Effects Analysis (DFMEA) is a systematic approach to identifying and addressing potential failure modes in a product design, aiming to reduce risks associated with those failures.
* Severity Classification Matrix:
* Used in DFMEA to prioritize risks based on their severity, occurrence, and detection, but not the most desirable outcome.
* Reduction in Design Risk:
* The primary goal of DFMEA is to identify potential failure modes and mitigate their impact, thereby reducing the overall risk in the design.
* This involves taking corrective actions to eliminate or reduce the likelihood of failures and their effects.
* Comprehensive List of Design Functions:
* Part of the DFMEA process but not the ultimate goal.
* Estimate of Failure Frequency:
* Important for assessing risk but secondary to actually reducing the risk.
References: DFMEA methodologies and best practices in design risk management.
NEW QUESTION # 90
An increase in the overall length of a recently qualified metal component has been observed and the quality engineer suspects that the storage temperature could be a factor that has affected the overall length. Which of the following tools could be used to assess this relationship?
- A. Affinity diagram
- B. Scatter diagram
- C. Histogram
- D. Cause and effect diagram
Answer: B
Explanation:
A scatter diagram is used to assess the relationship between two variables. In this case, it can be used to analyze the relationship between storage temperature and the overall length of the metalcomponent. A scatter diagram helps in visualizing any correlation between the two variables. Reference: "The Quality Toolbox" by Nancy R. Tague, which provides descriptions and uses for various quality tools including scatter diagrams.
