Question 1
4 out of 4 points
Suppose we wish
to determine
whether, in the
population, Y (the
dependent
variable) is
negatively related
to X (the
independent
variable). We
draw a random
sample.
One observation
has an X value of
175 and a Y value
of -185.
Another
observation has an
X value of 200
and a Y value of
-100.
Another
observation has an
X value of 100
and a Y value of
-50.
Another
observation has an
X value of 100
and a Y value of
50.
Another
observation has an
X value of 25 and
a Y value of 50.
Based on these
data, what
conclusion can we
reach? (Use an
alpha level of .
05 .)

Question 2
4 out of 4 points
Suppose we wish
to determine
whether, in the
population, Y (the
dependent
variable) is
negatively related
to X (the
independent
variable). We
draw a random
sample.
One observation
has an X value of
175 and a Y value
of 298.
Another
observation has an
X value of 200
and a Y value of
200.
Another
observation has an
X value of 100
and a Y value of
100.
Another
observation has an
X value of 100
and a Y value of
50.
Another
observation has an
X value of 25 and
a Y value of 50.
Based on these
data, what
conclusion can we
reach? (Use an

alpha level of .

Question 3
4 out of 4 points
Suppose we wish
to determine
whether, in the
population, Y (the
dependent
variable) is
positively related
to X (the
independent
variable). We
draw a random
sample.
One observation
has an X value of
25 and a Y value
of 232.
Another
observation has an
X value of 100
and a Y value of
175.
Another
observation has an
X value of 100
and a Y value of
100.
Another
observation has an
X value of 175
and a Y value of
100.
Another
observation has an
X value of 200
and a Y value of

25.
Based on these
data, what
conclusion can we
reach? (Use an
alpha level of .
05 .)
