Question

You want to know if the medicaid expansion in New Hampshire improved the self reported health scores of the people that were included. You survey a group of 50 people and have them report their health from 0 to 800 through a series of questions. The sample had a mean score of 500 and a standard deviation of 100. Using this information, test the null hypothesis that the self reported health in this sample is not different than the baseline of 450. Select the best conclusion.

A. Because the critical value exceeds the test statistic, we reject the null and conclude that they are significantly different.

B. Because the critical value exceeds the test statistic, we fail to reject the null.

C. Because the test statistic exceeds the critical value, we reject the null and conclude that they are significantly different.

D. Because the test statistic exceeds the critical value, we fail to reject the null.
