Question

As a sales manager of your company you decided to examine if the sales (in quantity), Q, is determined by your own product price ( in dollars), P, advertisement expenditure ( in million dollars), A, and consumers average income (in 1,000 dollars), Y, you estimated a multiple regression equation of:
Q= a + bP + cA + dY where a, b, c, and d are coefficients.

Explanation / Answer

SSR = 208

SSres = 52

SST = SSR + SSres = 208 + 52 = 260

R^2 = SSR / SST = 208 / 260 = 0.8

So correct option is . 0.8
