A medical researches wishes to see if the variance of the heart rates (in beats per minute) of smokers is different from the variance of heart rates of people who do not smoke. A sample of 12 nonsmokers yielded a variance of 10. A sample of 10 smokers yielded a variance of 36. Using a = 0.10, is there enough evidence to support the claim? A. Determine the test statistic. B. Determine the critical value. C. Determine the p value. Report to 4 decimal places. D. What is the decision? O Reject the null hypothesis O Fail to reject the null hypothesis
