a) here option B is correct. See here we are interested in the proportion of US adults who have positive opinion about media. So here, there is only one group, that is the group of US adults. In this group we are interested in knowing the proportion of individuals who have positive opinion about media. So option B is correct and A is wrong. b) Here option A is correct. Here we have two group of inviduals: Group 1. Female students of the university. Group 2. Male students of the university.
