Among students at a nearby college, the proportion who say they're interested in their congressional district's election results has traditionally been 70%. After a series of lackluster debates on campus, a political scientist claims that the proportion, p, of students at the college who say they're interested in their district's election results is now less than 70%. A poll is commissioned, and 168 out of a random sample of 245 students at the college say they're interested in their district's election results. Is there enough evidence to support the political scientist's claim at the 0.10 level of significance?
