He has devised the following regression equation:
Y = 23.95 X 1 + 24.44 X 2 - 41.44
Where X 1 is the number of cartons per shipment and X 2 is the size of the cartons.
a. Interpret each of the values in the regression equation.
b. Is multiple regression appropriate in this situation If yes, why If no, why not
