Answer:

hello your question is incomplete, the missing part of the question is attached below

answer :

1) β1 = 0.25

β2 = 4.85

2) 40.55 + 0.25 ( math score ) + 4.85 ( hours )

Explanation:

1) The estimate for β1 and β2

From the attached excel result the estimates are ;

β1 = 0.25 : This shows the change in the mean value of the final score in relation to the change in math score while the time is kept constant

β2 = 4.85 : This represents the change in the mean value of the final score in relation to the change in time while the math score is held constant

2) sample regression equation

The Final sample regression equation = 40.55 + 0.25 ( math score ) + 4.85 ( hours )
