What methods are you going to use to answer the research question? State your chosen method and check ALL assumptions (if you are using the normal distribution).
Answer: Chi-Squared Test;
Assumptions: Independence - subjects are independent; one person’s response does not impact another person’s response. The expected count in each cell are greater than or equal to 5. H0 = There is No relationship between those who do or do not have insurance and their self-reported race HA = There is a relationship between those who do or do not have insurance and their self-reported race
What was the test-statistic? Answer: X-squared = 13.788, df = 3, p-value = 0.003208
What was the p-value? Answer: p-value = 0.003208
Interpret your results in the context of the problem (i.e., in a way that a non-statistician could understand). Include relevant tables AND figures.
