I need assitance in figuring out how to come up with the answers to this ANOVA table. I need the calculation on how to find the answers.
ANOVA table: Problem type 2
The marketing research department of a large company knows that the company's monthly sales are influenced by the way in which it spends money on marketing. For example, monthly expenditures such as
x1 = money spent on television advertising (in 's of dollars)
x2 = money spent on promotion (i.e. free samples)
x3 = money spent on newspaper advertising (in 's of dollars)
x4 = average discounts offered to retail outlets (in %)
and several others are known to have an effect on , the company's total monthly sales (in millions of dollars). Using data from the previous months, the company decides to collect data on of the independent variables to use in a multiple regression model for estimating monthly sales. If the for this model is , fill in the missing entries in the ANOVA table associated with this model: Do all calculations to at least three decimal places.

Source of Variation Degrees of Freedom Sum of Squares Mean Squares F Statistic
Regression 3 204 68 [need calc.]
Error 11 [need calc.] [need calc.]
Total 14 [need calc.]

If I can figure out the sum of squares, I can figure out the mean square and the F statistic.

Thank you.
