(a) Build a Pivot table that shows the number of counties that supported the Republican candidate in 2016 with support of 0-9.99%, 10-19.99%, 20-29.99%, etc.

(b) How much more likely is a county to vote Democratic in the 2016 election, given that at least 10% of the population has a graduate degree? Hint: Think odds ratio.

(c) Are these results statistically significant? That is, conduct a 2 test and state your results in terms of a hypothesis test and p-value.

(d) What is the danger of making these types of observations (questions b and c) without further statistical analysis?
