Question
In a certain statistics class the past data has indicated that there is a positive, linear relationship between a student's midterm test score and their subsequent final test score. The regression model for this relationship is given by:
final score = 40 + 0.6*(midterm score)
From the choices below, the best interpretation of the intercept is:
-A student who scored a 0 on the final is expected to score a 40 on the midterm
-For every additional 1-point increase in a student's midterm score, the corresponding final test score increases by 0.6 points
-For every additional 1-point increase in a student's final test score, the corresponding midterm score increases by 0.6 points
-If the final test score is a 0, the expected midterm score would be 67
-A student who scored a 0 on the midterm is expected to score a 40 on the final
-If the final test score is a 0, the expected midterm score would be -67
