To assess the p-value, we consider that the test statistic given is a z statistic for a comparison of two proportions (American vs international students in Greek life). The approximate two-tailed p-value is determined by P(|Z| > 1.75).
Option 1: 0.05 < p-value < 0.10. Since a Z of 1.75 yi......Login to view full explanation登录即可查看完整答案
