A news article reports: college graduates live longer than non-college graduates. You want to test this, and so you collect some data on education and living past 90: Lived past 90 Did not live past 90 Row total Graduated college 10 28 38 Did not graduate 12 50 62 Column total 22 78 100 Do those who graduated college live longer (ie. are the proportion of graduates who live past 90 larger than the proportion of non-graduates who live past 90?) Test this hypothesis at the a = .05 level 1. State the assumptions ( i.e., sample size, sample size >
