Nicotine Patches Are Often Used To Help Smokers Quit Does Giving Medicine To Fight Depression Also Help A Randomized D 1 (46.41 KiB) Viewed 84 times

Nicotine patches are often used to help smokers quit. Does giving medicine to fight depression also help? A randomized double-blind experiment assigned 239 smokers to receive nicotine patches and another 223 to receive both a patch and the antidepressant drug bupropion. After a year, 43 subjets in the nicotine patch group had abstained from smoking, as had 72 in the patch-plus-drug group. a) Construct a 90% confidence interval for the difference in the proportion of smokers who abstain from smoking when using buproprion and a nicotine patch and the proportion who abstain when using only a patch. (4 decimal places) b) Based only on this interval, do you think that the difference in proportion of abstaining smokers is statistically significant (at a = 0.100)? Yes, because o is not contained within my 90% confidence interval, I am 90% confident that the difference between the proportion abstaining using only the patch and the proportion abstaining using the patch-plus-drug is not 0, so there is a difference. Yes, because o is contained within my 90% confidence interval, it is possible that the difference between the proportion abstaining using only the patch and the proportion abstaining using the patch-plus-drug is 0, meaning that it is possible that there is a difference. O No, because o is contained within my 90% confidence interval, it is possible that the difference between the proportion abstaining using only the patch and the proportion abstaining using the patch-plus-drug is o, meaning that it is possible that there is no difference. No, because o is not contained within my 90% confidence interval, so I am 90% confident that the difference between the proportion abstaining using only the patch and the proportion abstaining using the patch-plus-drug is o, so there is not a difference.
