Suppose the (population) covariance and correlation between two variables X and Y is given by 20 and .6, respectively, and the (population) covariance and correlation between two variables X and Z is given by 200 and .3, respectively. Then

	a.	There is a positive relationship between both X and Y, as well as X and Z, but the relationship is stronger between X and Y because they exhibit a higher covariance.
	b.	There is a positive relationship between both X and Y, as well as X and Z, but the relative strenghts of these relationships cannot be determined.
	c.	Although there is a high covariance between both X and Y, as well as between X and Z, we cannot determine whether it is positive or negative because the correlations are too small.
	d.	There is a positive relationship between both X and Y, as well as X and Z, but the relationship is stronger between X and Y because they exhibit a higher correlation.
	e.	none of these options
