:2. Consider the following two statements about a scatter
diagram. <p>

A. If the correlation coefficient is -0.75, below-average    
   values of the dependent variable tend to be associated    
   with below-average values of the independent variable.  <p>

B. If the dependent variable is usually less than the        
       independent varia ble, the corre lation coeff icient has
       to be negat ive. <p>

Then <p>

a. Both statements are true. <p>

b. Both statements are false. <p>

c. Statement A is true but statement B is false.  <p>

d. Statement B is true but statement A is false. 
             <p>
