A multiple regression line between mid termscores $\left(y^{\prime}\right.$, as dependent variable), hours worked $(H)$, and the number of classes attended $(c)$ is found to be $y^{\prime}=20+10 * h+5 * c$. This implies that
A)all other things remaining the same, actual midterm score will be higher by 5 points for those who . attended 11 classes as compared to those who attended 10 classes
B)all other things remaining the same, estimated midterm score will be higher by 5 points for those who . attended 11 classes as compared to those who attended 10 classes
C)all other things remaining the same, actual midterm score will be higher by 10 points for those who . worked for 8 hours as compared to those who worked for 7 hours
D)all other things remaining the same, estimated midterm score will be higher by 10 points for those who . worked for 8 hours as compared to those who worked for 7 hours
E) B and D

Quizplus · Accepted Answer

The correct answer is E) B and D. This is because the regression equation given implies that for each additional class attended (holding hours worked constant), the estimated midterm score will increase by 5 points. Similarly, for each additional hour worked (holding the number of classes attended constant), the estimated midterm score will increase by 10 points. Therefore, the estimated midterm score will be higher by 5 points for those who attended 11 classes as compared to those who attended 10 classes, and the estimated midterm score will be higher by 10 points for those who worked for 8 hours as compared to those who worked for 7 hours.
