An environmental science professor at UNL was curious whether the majority (more than half) of students at UNL regularly recycle plastic bottles. The professor selected a random sample of 146 students at UNL to interview, then asked each student: "Do you recycle plastic bottles more often than you throw them in the trash?" (Yes/No). Suppose that 89 of the students answered "Yes".
