You are examining the relationship between advertising.spending (X) and sales revenue (Y) for a product. The true population model is given by: Yi = 0+1Xi + Ei Where: Yi: Sales revenue for observation i Xi: Advertising spending for observation i (a) Interpret the coefficient 30 in the context of this problem. (b) Interpret the coefficient 1 in the context of this problem. (c) What are some of the things that would be included in our error term (include at least 2)? Explain. (d) Suppose you use a sample from this population for estimation. Write up an equation to show the predicted model. (e) Did you include an error term in your predicted model? Explain why or why not.
