How many runs would be required in a complete factorial design if there are four
levels and three factors?
A) 64
B) 7
C) 12
D) 81

A. 64. If there are four levels and three factors in a complete factorial
design, 64 runs would be required. The number of required runs is
calculated by raising the number of levels to a power equal to the number
of factors. In this case, then, the calculation is performed 43 = 64. If the
complete factorial design had five levels and three factors, the number of
runs would be calculated 53 = 125.
If a Histogram displays two peaks the distribution would likely be _____________.

, Which type of diagram is used to eliminate unnecessary movement during a process?
A) Scatter diagram
B) Spaghetti diagram
C) Ishikawa diagram
D) Matrix diagram

A. Spaghetti diagram. A spaghetti diagram indicates the physical travel of
employees, resources, and equipment during a process. These diagrams
are used to identify unnecessary movements and to streamline processes
as much as possible. A scatter diagram displays the correlation between
two variables, with the independent variable on the x-axis and the
dependent variable on the y-axis. An Ishikawa diagram, also known as a
fishbone or cause-and-effect diagram, is used to outline the causes of a
particular event, as well as the possible results of particular actions. Finally,
a matrix diagram depicts the relationships between a group of different
items in several groups. A matrix diagram looks a great deal like a table of
data, with the strength between relationships indicated by the values in
each cell.
A two-sample T-test does which of the following?
a) Compares the medians to determine if sample 1 is statistically difference from
sample 2
b) Subtracts the mean of sample 1 from sample 2 and compares the difference to zero
to determine if they are equal
c) Compares the means to determine if sample 1 is statistically difference from sample
2
d) test of the difference between two population medians
