Many over-the-counter decongestants and appetite suppressants contain the ingeredient phenylpropanolamine. A study was conducted to investigate whether this ingredient is associated with strokes. The study found that 6 of 702 stroke victims had used an appetite suppressant containing phenylpropanolamine, compared to only 1 of 1,376 subjects in a control group. The following table summarizes the data. Using the output from R, interpret the 95% confidence for the population value of the odds ratio. Phenylprop. No Phenylprop. Yes 6 696 Stroke? No 1 1375 Total 702 1376 Fisher's Exact Test for Count Data data: mat 95 percent confidence interval: 1 432221 544. 120590 sample estimates odds ratio 11 84188 O A. We are 95% confident that the true odds of stroke is between 1.43 and 544. 12 times higher for those not using an appetite suppressant containing phenylpropanolamine than for those using an appetite suppressant containing phenylpropanolamine O B. With 95% confidence, we are uncertain which population has a higher odds for stroke. If it higher for those who take an appetite suppressant containing phenylpropanolamine, it is by as much as 544. 12 times. If it is higher for those not taking an appetite suppressant, then is is by as much as 1 43 times. O C. We are 95% confident that the true odds of stroke is between 1 43 and 544 12 times higher for those using an appetite suppressant containing phenylpropanolamine than for those not using an appetite suppressant containing phenylpropanolamine
