• Estimating a Population Proportion

Question: In a program designed to help patients stop smoking, 198 patients were given sustained care, and 82.8% of them were no longer smoking after one month. Among 199 patients that were given standard care 62.8%were no longer smoking after one month (based on the data from "sustained Care Intervention and Post Discharge Smoking Cessation Among Hospitalized Adults " by Rigotti, journal of the American Medical Association.

1.) Construct 95% confidence interval estimates of the percentage of success from sustained care. Interpret the result in the context of this problem.

2.) Construct 95% confidence interval estimates of the percentage of success from standard care. Interpret the result in the context of this problem.

3.) Compare the results. What do you conclude?
