Six Sigma Green Belt Practice Questions with
answers
A shoe manufacturing firm learned through a Lean Six Sigma project
their boot soles could be made of a different material requiring two
less steps in the process. Removal of these two steps yielded a
monthly cost savings of $7,500. Therefore the reported financial
savings for this LSS project were:
A) $45,000
B) $75,000
C) $90,000
D) $120,000 - CORRECT ANSWERS ✔✔This is a bizarre question. It
never mentions that the financial savings should be reported at the
annual level. However, that's a reasonable assumption to make.
$7,500 * 12 months = $90, 000.
The statistics that summarize a population are referred to as
(A) categorical statistics
(B) descriptive statistics
(C) probabilistic statistics
(D) control statistics - CORRECT ANSWERS ✔✔B. Descriptive
Statistics
,As we calibrate our Measurement System to assure accurate data we
frequently encounter Bias which is the __________________ of a
measured value from the ________________ value. (Taken from
Iassc sample Green Belt exam.)
(A) Spread, Mean of the population
(B) Deviation, hoped for
(C) Deviation, true
(D) Spread, idea - CORRECT ANSWERS ✔✔C. Deviation, True
When calculating the Cp index, what does the standard deviation
represent in the formula Cp = (USL - LSL) / 6σ?
(A) The tolerance interval
(B) The confidence interval for the result
(C) The range of the process
(D) The variance of the index - CORRECT ANSWERS ✔✔C. The
range of the process
In an "X" Sifting exercises a Belt will use a(n) _______________ to
assist in isolating families of variation that may exist within a
subgroup, between subgroups or vary over time.
(A) Multi - Vari Chart
(B) Pareto Chart
, (C) FMEA
(D) Shewhart Analysis - CORRECT ANSWERS ✔✔A. Multi - Vari
Chart
When an inspection process rejects conforming product, what type of
error is being made?
(A) a
(B) b
(C) σ
(D) H0 - CORRECT ANSWERS ✔✔A. Alpha error
Which of the following terms is used to describe the risk of a type I
error in a hypothesis test?
(A) Power
(B) Confidence level
(C) Level of significance
(D) Beta risk - CORRECT ANSWERS ✔✔C. Level of Significance
Which of the following is a commonly accepted level for alpha risk?
(A) 0.05
(B) 0.50
(C) 0.70
