質問 # 48
An electronics firm was experiencing high rejections in their multiple connector manufacturing departments. "p" charts were introduced as part of a program to reduce defectives. Control limits were based on prior history, using the formula:
P' is the historical value of percent defective and n is the number of pieces inspected each week. After six weeks, the following record was accumulated
1,000 pieces were inspected each week in each department. Which department(s) exhibited a point or points out of control during this period (round off calculations to nearest tenth of a percentage point)?
- A. Department 106.
- B. All of the department.
- C. Department 105.
- D. Department 104.
正解：B

質問 # 51
The risk priority number (RPN) is determined by the
- A. product of reliability value, criticality number, and failure mode
- B. product of frequency of the occurrence, severity, and detection ratings
- C. sum of reliability value, criticality number, and failure mode
- D. sum of frequency of the occurrence, severity, and detection ratings
正解：B
解説：
The Risk Priority Number (RPN) in FMEA is determined by the product of the frequency of occurrence, severity, and detection ratings. This multiplication helps in quantifying the risk associated with each potential failure mode, allowing for prioritization of corrective actions based on the highest risk areas.
質問 # 52 
A in this drawing, the symbol is being used to indicate the
- A. datum
- B. feature
- C. basic definition
- D. reference plane
正解：A
解説：
In the provided drawing, the symbol marked "A" is being used to indicate a datum. A datum is a reference point, line, or surface used as a basis for measurement and to establish the location or orientation of other features. It serves as a starting point for dimensional control and ensures consistency in the manufacturing process.
質問 # 53
A two-way analysis of variance has r levels for one variable and c levels for the second variable with 2 observations per cell. The degree of freedom for interaction is
- A. 2(r-1)(c-1)
- B. 2(r)(c)
- C. (r-1)(c-1)
- D. rc-1
正解：C

I. Microwave.
II. Magnetic particle.
III. Pulse echo.
IV. Eddy current.
- A. III and IV only
- B. I, II and IV only
- C. I and IV only
- D. I and III only
正解：A
質問 # 55
A system was designed with 3 capacitors. When the system is first activated all capacitors are operating.
The system continues to operate as long as at least 1 capacitor is operating. This is an example of
- A. A series system.
- B. Redundancy.
- C. An active parallel system.
- D. A standby parallel system.
正解：C
質問 # 56
A company uses four components (W. X. Y. and Z) to create its final product. The source and time factors for these components are listed below. What is die critical path for this company's final product?
ComponentSourceAcquisition TimeInstallation TimePredecessor Steps
WInternaln/a4 weeksNone
XExternal5 weeks4 weeksNone
YInternaln/a4 weeksW.X.Z
ZInternaln/a6 weeksNone
- A. 13 weeks
- B. 9 weeks
- C. 8 weeks
- D. 6 weeks
正解：A
解説：
The critical path is the longest path through the project, determining the shortest time to complete the project.
The components and their dependencies are:
* W: Installation Time = 4 weeks
* X: Acquisition Time = 5 weeks + Installation Time = 4 weeks, Total = 9 weeks
* Y: Predecessors are W, X, Z. Therefore, Y cannot start until W, X, and Z are completed.
* Z: Installation Time = 6 weeks
To find the critical path:
* W: 4 weeks
* X: 9 weeks
* Z: 6 weeks
Y depends on W, X, and Z, so Y starts after the longest time among W, X, and Z, which is 9 weeks (X), and Y takes 4 weeks. Thus, the total time is 9 weeks + 4 weeks = 13 weeks.

. To determine when to make proactive adjustments to a process.
. To differentiate between major and minor problem areas.
. To gather data and to design experimental controlled changes.
. To evaluate the results of other problem solving techniques upon the product or service.
- A. II and III only
- B. II and IV only
- C. I, II, III and IV
- D. I and II only
正解：B
質問 # 59
A company incurred the following quality costs last month.
Incoming material inspection$5,000
Process scrap$3,000
In-process reworkS450
Control engineering$450
Warranty$2,000
Customer complaints$6,000
Product liability$1,000
What is the total cost of external failures?
- A. $8000
- B. $6000
- C. $9450
- D. $9000
正解：D
解説：
The total cost of external failures includes warranty, customer complaints, and product liability. Summing these costs:
* Warranty: $2,000
* Customer complaints: $6,000
* Product liability: $1,000
Total external failure cost = $2,000 + $6,000 + $1,000 = $9,000
