Next, we will examine an entirely different question. Do the states that voted for McCain have a different average percent of heavy drinkers than the states that voted for Obama in the 2008 election.

1. This table also performs an F-test for the equality of the standard deviation. If we want to test if the standard deviation of the McCain states is the same as the standard deviation of the Obama states, what would be our hypotheses?

2. The test statistic for the F-test is labeled F, and the p-value is next to it, labeled Sig. SPSS uses a slightly different test for checking if the standard deviations are equal so the test statistic will not match the one we would find by hand using an equation. Report the test statistic and the p-value.

3. At a significance level of .05, can we reject the null hypothesis? Write a conclusion.
