Use the accompanying set of dependent and independent variab

Use the accompanying set of dependent and independent variables to complete parts a through c below. Using technology, construct a multiple regression model with the given data.

Solution

Using statistical software the multiple regression equation for the given model.

taking \'Y\' as dependent variable and X1,X2 are independent variable.

The regression equation is y = 15.07 + 1.0045 x1 - 0.4185 x2
