Bias in Clinical Trials? Researchers investigated the issue of race and equality of access to clinical trials. The following table shows the population distribution and the numbers of participants in clinical trials involving lung cancer (based on data from “Participation in Cancer Clinical Trials,” by Murthy, Krumholz, and Gross, Journal of the American Medical Association, Vol. 291, No. 22). Use a 0.01 significance level to test the claim that the distribution of clinical trial participants fits well with the population distribution. Is there a race/ethnic group that appears to be very underrepresented?
5. What does the level of significance represent in a test of hypothesis?
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. To answer the question of whether McCain states and Obama states have different average percent, heavy drinkers, we will use a 2 sample t-test. Why?
2. What should the hypotheses be for this test?
