Q1
A complete system of quality control: Is defined by critical control points, inspectors,
measurements, costs, and other considerations Involves a zero defects philosophy Requires a
continuous scale for measurement of defects Must include both variable and attribute
measurements
Answer: A. Is defined by critical control points, inspectors, measurements, costs, and
other considerations
Q2
Sampling inspection by attributes: Means each item sampled is classified as defective or not
defective based on quality standards Could be used together with process control and variable
measurement as part of a quality control system Utilizes a discrete scale of measurement a, b,
and c
Answer: D. a, b, and c
Q3

Q8
A process control chart: Assumes that 99.74% of special cause variation will fall between upper
and lower limits Has upper and lower control limits set at ± 2 standard deviations from the
center line Separates the assignable cause of variation from the common cause of variation
Assigns causes of variation to operator, machine, or material
Answer: C. Separates the assignable cause of variation from the common cause of
variation
Q9
A Pareto chart: Shows causes and effects of quality problems Shows the prevalence of the
various types of defects that have been found Is not useful when first studying a quality
problem Has both upper and lower specification limits
Answer: B. Shows the prevalence of the various types of defects that have been found
Q10
A cause-and-effect diagram: Identifies common causes of quality defects Is often used in
conjunction with a Pareto chart Is also called a fishbone diagram All of the above are true
Answer: D. All of the above are true
Q11
One of the earliest steps in designing a quality control system is to decide on: The amount of
inspection to use Who should do the inspection The type of measurement to be used Training
workers to perform inspection on their own work
Answer: C. The type of measurement to be used
