Question
In a survey of 1120 new college graduates 281 had a professional job on graduation day.
One 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:
(a) Ho :p= .24 vs. H1 : p< .24
(b) Но : р%3.24 vs. Hi:р#.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:
(а) 2.109
(b) .011
(c) .841
(d) 28.141
(е) .854
