From the result of the multiple regression analysis attached. The slope Coefficient of each independent variable is :
Television = 2.38 ; Newspaper = 1.45 and Mail = 1.82.
This slope values are the rate at which the dependent variable changes per unit increase in each of the independent variable.
Newapaper has the least slope Coefficient value of the 3 independent variables and hence will have the least significant effect on the value of revenue.
