(16) A regression model is estimated to be Y = 4 + 2X What is the predicted value of Y if X = 10? What is the impact on Y if X is increased by 1 unit?
We have given regression equation is ,
Y = 4 + 2X
For X= 10 , Substitute X=10 in above regression equation ,
=> Y= 4 + 2 (10)
=24
Therefore, predicted value for Y is 24 if X=10
Slope = 2
if X increases by 1 unit then Y will increase by 2 units.
