Comparing two data sets, you state in a memo to your supervisor
that data set B has a comparatively larger spread or variance.
Data set A: mean = 42.5, std deviation = 68.0, coefficient of
variation = 1.6
Data set B: mean = 28.9, std deviation = 60.7, coefficient of
variation = 2.1
Your incredulous supervisor says that you must be wrong since
data set A clearly has a higher standard deviation. Provide an
argument supporting your contention...

Given two sets A and B, the
intersection of these sets, denoted A ∩
B, is the set containing the elements that are in both
A and B. That is, A ∩ B =
{x : x ∈ A and x ∈
B}.
Two sets A and B are
disjoint if they have no elements in common. That
is, if A ∩ B = ∅.
Given two sets A and B, the union of
these sets, denoted A ∪ B,...

A dot plot has a horizontal axis labeled from 4 to 10 in increments
of 1. The graph consists of a series of plotted points from left to
right. The coordinates of the plotted points are as follows, where
the label is listed first and the number of dots is listed second:
5, 1; 6, 4; 7, 5; 8, 4; 9, 1.

Data Set A- 7,7,7,9,9,9,10
Data Set B- 4,6,6,6,8,9,9,9,10,10,10
Step 1
Create a bar graph that examines a variable or variables in
your data set.
Step 2
Find the sample mean, median (if it exists) mode for each set
of data
Next find the sample standard deviations for each set of
data
Create a box and whisker plot for each variable for each set
data
Eliminate any outliers from the samples. Redo part 1 for each
variable (if necessary, if not...
