It is claimed that the proportion of OSU students who belong to a fraternity or a sorority is 0.15. A college administrator has some reason to question this claim, and she gathers data from a random sample of 200 students in order to test Ho: p = 0.15 against Ha: p ≠ 0.15.  If the resulting test statistic is 0.9, what will the P-value be?   0.8159 0.1841 0.0180 0.0090 0.3682
