1.Non-linear functional forms:

a)Estimate a quadratic regression model where the outcome of interest is cigarette consumptionand the predictor variable is the price of a pack ofcigarettes.

b)Estimate the effect of an increase in the price of a pack of cigarettes from $4 to$5.

c)Provide a scatterplot that includes the estimated regression equation for the quadraticmodel.

d)Estimate a linear-log regression model where the outcome of interest is cigarette consumptionand the predictor is the price of a pack ofcigarettes.

e)Estimate the effect of an increase in the price of a pack of cigarettes from $4 to$5.

f)Provide a scatterplot that includes the estimated regression equation for the linear-logmodel.

g)Which model provides a better fit to the data? The quadratic or linear-log model? Which modeldo you think is more appropriate from a theoreticalperspective?
