Step Two: Respond

After reviewing the data, respond to the following questions in this discussion forum:

1. Conduct a chi-square test of independence for "States Voting for Barack Obama" and its effect on Medicaid Expansion. State a null and alternative hypothesis. Use a significance level of 0.05. Write a paragraph detailing the conclusion you draw from your results (75-100 words).
2. What criticism might you have of the data analysis? Researchers might take issue with the variables chosen, or the setup of this particular test. There are no wrong answers, here, but your reasoning should be supported by statistical theory or supporting evidence. (50-75 words)
