Question

refer to the accompanying scatterplot. the four points in the lower left corner are measurements from woman, and the four points in the upper right corner are from men. completes parts (a) through (e) below.

a. examine the pattern of the four points in the lower left corner (from women) only, and subjectively determine whether there appears to be a correlation between x and y for women. choose the correct answer below.

a. there does not appear to be a linear correlation because the points do not form a line.
b. there appears to be a linear correlation because the points form an obvious pattern.
c. there appears to be a linear correlation because the points form a line.
d. there does not appear to be a linear correlation because the points form an obvious pattern.

b. examine the pattern of the four points in the upper right corner (from men) only, and subjectively determine whether there appears to be a correlation between x and y for men. choose the correct answer below.

a. there appears to be a linear correlation because the points form an obvious pattern.
b. there does not appear to be a linear correlation because the points do not form a line.
c. there appears to be a linear correlation because the points form a line.
d. there does not appear to be a linear correlation because the points form an obvious pattern.

Explanation:

For part (a), the four points for women (lower left corner) are clustered without an obvious linear trend, so no linear correlation appears. For part (b), the four points for men (upper right corner) are also clustered without a linear pattern, so no linear correlation appears.

Answer:

a. A. There does not appear to be a linear correlation because the points do not form a line.
b. B. There does not appear to be a linear correlation because the points do not form a line.
