a- is listed 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.

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= ___

d- Do the four points in the upper right corner have the same correlation?coefficient?

e- 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 ? = 0.05. The correlation coefficient for all eight points is r= ___

f- Using ?=0.05 what does r suggest about the relationship between x and?y?

g- Based on the preceding?results, what can be?concluded? Should the data from women and the data from men be

considered?together, or do they appear to represent two different and distinct

populations that should be analyzed?separately?
