22.18 First-year students. A UCLA survey of college freshmen in the 2014–2015 academic year found that 19.4% of all first-year college students identify themselves as politically conservative. You wonder if this percentage is different at your school, but you have no idea whether it is higher or lower. You plan a sample survey of first-year students at your school. What hypotheses will you test to see if your school differs significantly from the UCLA survey result?
