Among college students, the proportion p who say they're interested in their congressional district's election results has
traditionally been 65%. After a series of debates on campuses, a political scientist claims that the proportion of college
students who say they're interested in their district's election results is more than 65%. A poll is commissioned, and 178
out of a random sample of 260 college students say they're interested in their district's election results. Is there enough
evidence to support the political scientist's claim at the 0.05 level of significance?
