i. State the null and research hypothesis ii. Make a decision based on the information provided iii. State the type of error that may exist under the condition. 1. The following table displays descriptive statistics on the participants involved in the study described in Problem 1. Characteristic | New Compound | Placebo | p-value Mean Age, years | 47.2 | 46.1 | 0.7564 % Males | 44% | 59% | 0.0215 Mean Body Mass Index | 24.7 | 25.1 | 0.0851 Are any of the characteristics significantly different between groups? Justify briefly. (Hint: No calculations, just interpret the above.)

Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, $P$ -value or critical value(s), then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 198 smokers who underwent a "sustained care" program, 51 were no longer smoking after six months. Among 199 smokers who underwent a "standard care" program, 30 were no longer smoking after six months (based on data from "Sustained Care Intervention and Postdischarge Smoking Cessation Among Hospitalized Adults," by Rigotti et al., Journal of the American Medical Association, Vol. 312, No. 7). We want to use a $0.01$ significance level to test the claim that the rate of success for smoking cessation is greater with the sustained care program. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. c. Does the difference between the two programs have practical significance?
