Let's practice interpreting p-value. (a) Asthma affects 7% of the population. The American Journal of Respiratory and Critical Care Medicine reported on a study designed to determine if for people who regularly taking aspirin, the percentage with asthma was lower than 7%. Of 2200 randomly selected individuals who regularly take aspirin, 5.7% had asthma. The test statistic for the study was -2.39 and the p-value was .0084. Which of the following is the best interpretation of the p-value? a. Assuming the true proportion of regular aspirin users having asthma is less than 0.07, the probability of selecting another sample of 2200 whose test statistic value is -2.39 or more negative is 0.0084. b. Assuming the true proportion of regular aspirin users having asthma is less than 0.07, the probability of selecting another sample of 2200 whose test statistic value is -2.39 or closer to 0 is 0.0084. c. Assuming the true proportion of regular aspirin users having asthma is 0.07, the probability of selecting another sample of 2200 whose test statistic value is -2.39 or more negative is 0.0084. d. Assuming the true proportion of regular aspirin users having asthma is 0.057, the probability of selecting another sample of 2200 whose test statistic value is -2.39 or closer to 0 is 0.0084. e. Assuming the true proportion of regular aspirin users having asthma is 0.057, the probability of selecting another sample of 2200 whose test statistic value is -2.39 or more negative is 0.0084.
