Question 9 Quit Smoking: Previous studies suggest that use of nicotine-replacement Type numbers in the boxes. therapies and antidepressants can help people stop smoking. The New Part 1: 5 points England Journal of Medicine published the results of a double-blind, placebo- |aby Part 2: 5 points controlled experiment to study the effect of nicotine patches and the 10 points antidepressant bupropion on quitting smoking. The target for quitting smoking was the 8th day of the experiment. In this experiment researchers randomly assigned smokers to treatments. Of the 162 smokers taking a placebo, 28 stopped smoking by the 8th day. Of the 272 smokers taking only the antidepressant buproprion, 82 stopped smoking by the 8th day. Calculate the 99% confidence interval to estimate the treatment effect of bupropion (placebo- treatment). (The standard error is about 0.0407. Use critical value z = 2.576.) Round your answer to three decimal places. Put lower bound in the first box and upper bound in the second box. Question 10 Gardeners on the west coast of the United States are investigating the Type numbers in the boxes. difference in survival rates of two flowering plants in drought climates. Plant 10 points A has a survival rate of 0.68 and plant B has a survival rate of 0.43. The standard error of the difference in proportions is 0.092. What is the margin of error for a 99% confidence interval? Use critical value z = 2.576. MOE = Round all calculations to three decimal places
