Imagine that two researchers independently carry out clinical trials to test the same null hypothesis, that COX-2 selective inhibitors (which are used to treat arthritis) have no effect on the risk of cardiac arrest. They use the same population for their study, but one experimenter uses a sample size of 60, and the other uses a sample size of 100. Assume that all other aspects of the studies, including significance levels are the same between the two studies. Which study has higher power? The larger, 100 subject study The smaller, 60 subject study. O The power of a test is not affected by the sample size.
