In a survey of 1120 new college graduates 281 had a professional job on graduation day. year ago the proportion of graduates with a professional job on graduation day was .24 or 24%. The setup of the null and alternative hypotheses to test whether there is sufficient evidence to conclude that the proportion of graduates with a professional job is higher now than it was one year ago is: One (a) Ho : p= .24 vs. H1 : p< .24 (b) Họ : p = .24 vs. H1 : p# .24 (c) Ho : p= .24 vs. H1 : p> .24 (d) Ho : p= .25 vs. H1 : p < .25 (e) Ho : p= .25 vs. H1 : p > .24 The value of the test statistic is: (a) 2.109 (b) .011 (c) .841 (d) 28.141 (e) .854
