2. How well does the model predict the Democratic Presidential Vote?
3. Interpret the coefficient on the variable "median income." What exactly does it tell you? Is the effect of "median income" on presidential voting statistically significant?
4. Use the model to predict the effect of a $5000 increase in a county's median household income on the Democratic share of the vote, holding other variables in the model constant. Be sure to indicate whether the change is an increase or a decrease.
5. The model contains variables measuring the percent age 65 and older and the percent age 18 to 24 in a county. The model does not include a variable measuring the percent aged 25 to 64. Why not?
