Explanation / Answer

1) The responsibilities of a Black Belt typically include all EXCEPT
d. Overseeing data collection and analysis.

2) The most technical training and knowledge in a typical six sigma organization would be associated with which of the following roles?

c. Master Black Belt

3) A process is known to produce 20% defective parts. The probability that there will be less than two defectives in a

sample of size 10 drawn from the lot is approximately
a. 0.376.

It follows binomial distribution

(excel formula: =BINOM.DIST(1,10,0.2,TRUE))

4) Select the correct statement from among the following: The diameter of a certain rod is normally distributed with a
mean of 1.20". The proportion of rods with diameters less than 1.0" is
correct ans are:
c. equal to the proportion of diameters larger than 1.40".
d. less than the proportion of diameters smaller than 0.5.

reason: since Normal distribution is symmetry about mean 1.2

5) A quality control inspector is assigned the task of assessing the quantity of defects per unit on electrical
distribution panels which have been randomly selected at the end of an assembly line. Which statistical
distribution would be most appropriate for analyzing data from the process?

b. Poisson
