Answer:
Step-by-step explanation:
Hello!
Using the variables:
Y: Sales of all branches of a major international corporation.
X: Advertising of all branches of a major international corporation.
The following regression model was estimated:
^Y= 5000 + 7.25Xi
You have to predict a certain value of Y given a value of X:
^Y/X=$ 30000
To do so all you have to do is replace the value in the formula of the regression line:
^Y= 5000 + 7.25*30000
^Y= $ 222500
With a budget difference of $30000 for advertising, the estimated sales difference is $2225000.
I hope it helps!
