Would being part of a support group that meets regularly help people who are wearing the nicotine patch actually quit smoking? A department that deals with health matters in the county conducted an experiment using a sample of several hundred volunteers who are planning to use the patch. The subjects were randomly
divided into two groups.
– People in Group 1 were given the patch and attended a weekly discussions meeting with
counselors and others trying to quit. People in Group 2 also used the patch but did not
participate in the counseling groups.
– After six months 46 of the 143 smokers in Group 1 and 30 of the 151 smokers in Group 2
had successfully stopped smoking.
Do these results suggest that such support groups could be an effective way to help people
stop smoking.Use the test of proprtions to address the claim.
