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

 	
 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. 

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

Then

 a. Both statements are true.

 b. Both statements are false.

 	
  c. Statement A is true but statement B is false. 

 	
  d. Statement B is true but statement A is false.
