SIX SIGMA BLACK BELT EXAM 2
QUESTIONS WITH 100% VERIFIED
CORRECT ANSWERS!!
The larger the standard deviation, the lower the required sample size.
False.
Larger sample sizes are required to obtain a higher desired confidence level.
True.
Bias, stability, and linearity are location-related measurement system errors.
True.
Calibration can correct repeatability and reproducibility problems.
False.
The difference between the observed mean of measurements and the true actual or
reference value is called _____.
Bias.
When there is a difference in bias throughout the operating range, the measurement system
has a problem with _____.
Linearity.
Ability of the measurement system to be consistent when the same item is measured
repeatedly under the same conditions by the same appraiser is called _____.
Repeatability.
When the same item is measured by different appraisers using the same methods and tools,
we expect the same readings. What is this called?
Reproducibility.
During the Measure phase, map the "as-is" process, as currently practiced.
, True.
If a process has 3 process steps (A, B, C) with respective processing rates of 3, 2 and 4 units
per hour, what is the throughput rate of this process?
2 units/hour.
If a process has 3 process steps (A, B, C) with respective processing rates 3, 2 and 4 units
per hour, which step is the bottleneck?
B.

which has a standard deviation of 2 inches. You want to be accurate within plus/minus half
inch. What is the required sample size?
62.
In attribute agreement analysis, you want to evaluate 3 agreements: % agreement between
appraisers, within appraisers, and with the expert or standard.
