Question: An experiment was designed by a market researcher to study the effects of two types of promotional expenditures on sales of a line of food products sold in supermarkets. Sixteen locations were selected at random for the test. The researcher collected data on three factors. The data is given below, where y = sales volume ($ ten thousands), x 1 = media expenditures ($ thousands), and x 2 = point-of-sale expenditures ($ thousands).

y: 8.74 10.53 10.99 11.97 12.74 12.83 14.69 15.30 16.11

x 1 : 2 2 2 2 3 3 3 3 4

x 2 : 2 3 4 5 2 3 4 5 2

y: 16.31 16.46 17.69 19.65 18.86 19.93 20.51

x 1 : 4 4 4 5 5 5 5

x 2 : 3 4 5 2 3 4 5

The following model is proposed:

Y = 0 + 1 x 1 + 2 x 2 +

Carry out a "complete" multiple regression analysis of this model. In addition

predict y for x 1 = 3, and x 2 = 3, and give a 95% C.I. for both Y|X, and E[Y|X].
