Refer to the accompanying scatterplot. The four points in the lower left corner are measurements from women, and the four points in the upper right corner are from men. Complete 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. O A. There appears to be a linear correlation because the points form a line. OB. There appears to be a linear correlation because the points form an obvious pattern. O c. There does not appear to be a linear correlation because the points form an obvious pattern. OD. There does not appear to be a linear correlation because the points do not form a line. 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. 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.
c. Find the linear correlation coefficient using only the four points in the lower left corner (for women). Will the four points in the upper right corner (for men) have the same linear correlation coefficient? The correlation coefficient for the points in the lower left corner is r= (Type an integer or a fraction.) Do the four points in the upper right corner have the same correlation coefficient? O A. Yes, because the four points in the upper right corner form a different pattern from the four points in the lower left corner. O B. Yes, because the four points in the upper right corner form the same pattern as the four points in the lower left corner. O c. No, because the four points in the upper right corner form the same pattern as the four points in the lower left corner. O D. No, because the four points in the upper right corner form a different pattern from the four points in the lower left corner. d. Find the value of the linear correlation coefficient using all eight points. What does that value suggest about the relationship between x and y? Use α = 0.05. The correlation coefficient for all eight points is r= (Round to three decimal places as needed.)
