A

Answer to Question 2

Rationale 1: If both scores varied in the same direction, the relationship would be positive.
Rationale 2: If both scores varied in the same direction, the coefficient would be positive.
Rationale 3: This would indicate no relationship between the variables and the correlation coefficient would be 0.
Rationale 4: This represents an inverse relationship as the value of one variable increased, the value of the other variable decreased.
