For the multiple regression model Y= 40+ 15X1 10X2+ 5X1X2, if X2 is known to be 5 units, and X1 was known to be 1
For the multiple regression model Y= 40+ 15X1 10X2+ 5X1X2, if X2 is known to be 5 units, and X1 was known to be 1 unit, then we expect the dependent variable to be 35 units. 60 units. 40 units. Cannot be determined. For the multiple regression model Y= 40+ 15X1 10X2+ 5X1X2, if X1 is known to increase by 5 units, then we expect the dependent variable to increase by 35 units. increase by 50 units. decrease by 40 units. 0 Cannot be determined.
