Boston-- Taking an antidepression medicine appears to double smokers' chance of kicking the habit, a study found. The Food and Drug Administration approved the marketeing of this medicine, called Zyban or bupropion, to help smokers in May. The results of several studies with the drug, including one published in today's issue of the New England Journal of Medicine, were made public then. The newly published study involved 615 volunteers who wanted to give up smoking and were not outwardly depressed. They took either Zyban or dummy (placebo) pills for 6 weeks. A year later, 23% of those getting Zyban were still off cigarettes, compared to the 12% in the control group.

The results of this experiment were significant at the 0.05 significance level. In your opinion, are the results practically significant? Justify your position.

In performing a test of significance, the researcher can choose between adopting a fixed significance level or calculating a P-value. Does it matter which approach is taken? If so, describe the circumstances when one should use each approach.

So we are going to multiply by 23% to figure out how many people taking zyban were off smoking right

Answer 15

yes

Answer 16

141.45

Answer 17

correct so that means that is under half of how many people taking it were off smoking so that means that the first part when it says in ur opinion i would say it is not significant because the amount was under half the amount of how many volunteers wanted off smoking
