  3. C

    average size of production lots

  4. D

    decision of the quality assurance manager

Show answer and explanation

Correct answer: A

Explanation

ANSI ASQ Z1.4 provides sampling procedures and tables for inspection by attributes.

The sample size for Level II inspection is determined based on the lot size to be inspected.

This standard specifies how to choose sample sizes and acceptance numbers based on lot size to ensure statistically valid sampling.

References:
ANSI/ASQ Z1.4-2008 "Sampling Procedures and Tables for Inspection by Attributes" explains
how sample sizes are derived from lot sizes.

Question 2 Single choice

Which of the following tools can be used to determine the time needed to install a new computer system?

  1. A

    Activity network diagram

  2. B

    Affinity diagram

  3. C

    Cause and effect diagram

  4. D

    Prioritization matrix

Show answer and explanation

Correct answer: A

Explanation

An Activity Network Diagram, also known as a project network diagram or a PERT (Program Evaluation Review Technique) chart, is a tool used in project management to schedule, organize, and coordinate tasks within a project. It helps in determining the time required to complete a project by identifying the sequence of activities, dependencies, and the critical path, which is essential for determining the total time needed for the installation of a new computer system.

Question 4 Single choice

In reliability testing, operating an item in order to stabilize its characteristics is known as

  1. A

    burn-in

  2. B

    infant mortality

  3. C

    debugging

  4. D

    derating

Show answer and explanation

Correct answer: A

Explanation

In reliability testing, operating an item to stabilize its characteristics is known as burn-in. This process helps in identifying and eliminating early-life failures by running the equipment for a specified period under controlled conditions, thus ensuring more reliable performance in actual use.

Question 5 Single choice

The following chart is being used to monitor a process. What do points X and Y.
and region Z represent on the chart?

  1. A

    Special causes of variation

  2. B

    Changes in raw materials

  3. C

    Common causes of variation

  4. D

    Statistically stable variation

Show answer and explanation

Correct answer: A

Explanation

The chart provided is a control chart used to monitor process variation over time.

Control charts have upper control limits (UCL) and lower control limits (LCL) that represent the threshold of acceptable variation.

Points X and Y, which lie outside the control limits, indicate special causes of variation. These are deviations caused by specific, identifiable factors rather than inherent process noise.

Region Z, where data points are consistently below the mean and approaching the LCL, suggests a trend indicating a shift due to special causes.

References:
According to ISO 9001 and the ASQ, control charts are utilized to detect special causes of
variation, which signal that a process is out of control and requires investigation.

Question 6 Single choice

If a distribution is skewed to the left, the median will always be

  1. A

    Less than the mean.

  2. B

    Between the mean and the mode.

  3. C

    Greater than the mode.

Question 8 Single choice

A process produces rejects at a rate of 6. If multiple samples of 5 are drawn from a population of 100.000.

what is the expected number of rejects per sample?

  1. A

    0.3

  2. B

    30.0

  3. C

    5,000.0

  4. D

    6,000.0

Show answer and explanation

Correct answer: A

Explanation

The expected number of rejects per sample can be calculated using the reject rate and the sample size.
Given a reject rate of 6% (or 0.06) and a sample size of 5:

Expected number of rejects per sample = 0.06 * 5 = 0.3
