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: H_0 : p =. 24 vs. H_1: p strict inequality. 24 H_0 : p =. 24 vs. H_1: p not equal sign.24 H_0 : p=. 24 vs. H_1 : p strict inequality.24 H_0 : p =.25 vs. H_1 : p strict inequality.25 H_0 : p=.25 vs H_1 : p strict inequality.24

Explanation / Answer

here we want to test this year graduate professional job is more than previous year proportion 0.24

so we put the null hypothesis:Ho:p=0.24

since we want to test weather proportion of graduate professional job is more or not

so alternateve hypothesis will be H1:p>0.24

this is one-tailed (right-tailed ) test

so answer well be (c)Ho:p=0.24 vs H1:p>0.24
