A researcher claims that less than 40 percent of Rutgers students are commuter. A consumer agency wants to test this claim. The agency takes a random sample of 240 students and finds that 120 of them commute. If the agency conducts hypothesis testing, it has to consider:

• A.one-tailed test
• B.two-tailed test
• C.one-tailed test because sample size is large
• D.two-tailed test because sample size is large
