To assist with your analysis, you are provided with data that was collected for 8 consecutive quarters and 6 geographic markets.
(a) Estimate a regression model that expresses sales as a function of price, income and competitor's price and population? Once you have estimates the regression model, (a) provide a clear interpretation of the "R2" and (b) the statistical significant of the overall regression. Be sure to explain if the overall regression is statistically significant at a 5% level and how you know that.
(b) Can you provide a clear, concise interpretation for the slope coefficient on price? Is that coefficient significantly different from zero? How do you know that?
(c) Can you provide a clear, concise interpretation for the slope coefficient on income
