Question

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. Based on the p-value, what decision would you make? Summarize your conclusions.

2. This table also gives a 95% confidence interval for the difference. Report the confidence interval and interpret it.
