Question ID:PT41 S1 Q5 Passage:Statistician:  Two major studies found no causal link between medical procedure¬†X and disorder Y, but these studies are flawed. One study looked at 1,000¬†people who had undergone procedure¬†X and the other study looked at 1,100 people who had undergone procedure¬†X. But because disorder Y occurs in only .02 percent of the population, researchers would need to include many more than 1,100 people in a study to detect even a doubling of the rate of disorder Y. Stem:Which one of the following most accurately expresses the main conclusion of the statistician's argument? Correct Answer Choice:BChoice A:Contrary to the findings of two major studies, there is reason to think that procedure¬†X causes disorder¬†Y. Choice B:Two studies that discovered no causal link between procedure X and disorder¬†Y are unsound. Choice C:Researchers should conduct more-extensive studies of procedure¬†X to determine whether the procedure is causally linked with disorder¬†Y. Choice D:The two studies cited did not reach a conclusion as to whether disorder Y results from procedure X. Choice E:Despite the opinions of many medical experts, it has not been established that there is a causal link between procedure¬†X and disorder¬†Y.
