Q1) 3.66% of students at university live on campus.  Random sample determined that 20 of 40 male students and 40 of 50 of female students lived on campus.  At.05 level of significance, is there enough evidence to conclude that difference exists between proportion of male students who live on campus and proportion of female students who live on campus?

a) No, there is not enough information to refuse hypothesis that proportion of male students who live on campus and proportion of female students who live on campus are same as the test value -1.65 is inside acceptance region (-1.96,1.96).

b) Yes, there is enough information to refuse hypothesis that proportion of male students who live on campus and proportion of female students who live on campus are same as the test value -3.15 is outside acceptance region (-1.96,1.96).

c) Yes, there is enough information to refuse hypothesis that proportion of male students who live on campus and proportion of female students who live on campus are the same as the test value -3.00 is outside acceptance region (-1.96,1.96).

d) No, there is not enough information to refuse hypothesis that proportion of male students who live on campus and proportion of female students who live on campus are same as the test value -0.30 is inside acceptance region (-1.96,1.96).
