A multiple regression model has the form $$Y = 70 - 14X_1 + 5X_2$$ As $$X_1$$ decreases by 1 unit (holding $$X_2$$ constant), Y is expected to increase by 5 units decrease by 5 units increase by 14 units decrease by 14 units

Step 1
The coefficient of $$X_1$$ is -14. This means that for every one unit increase in $$X_1$$, Y decreases by 14 units. Show more…

A multiple regression model has the form y with hat on top= 12 – 4 x1 + 5 x2. As x1 increases by 7 units (holding x2 constant), y with hat on top is expected to (enter increase, decrease) by units.

For the multiple regression model [Y = 40 + 15X1 - 10X2 + 5X1X2], if X2 were to increase by 5 units and X1 were to increase by 1 unit, then we expect the dependent variable to: a) Decrease by 35 units. b) Decrease by 60 units. c) Increase by 60 units. d) Cannot be determined.
