Question

70% of students at a university live on campus. A random sample found that 31 of 50 male students and 41 of 55 of female students lived on campus. At the .05 level of significance, is there sufficient evidence to conclude that a difference exists between the proportion of male students who live on campus and the proportion of female students who live on campus?

Answer #1

USING THE TRADITIONAL 5-TEP PROCESS (NO P VALUE)
A random sample found that 37 of 60 male students and 42 of 55
of female students lived on campus. At the α = .01 level of
significance, is there sufficient evidence to conclude that a
difference exists between the proportion of male students who live
on campus and the proportion of female students who live on
campus?

please show all work:
68% of students at a university live on campus. A random sample
found that 23 of 45 male students and 42 of 55 of female students
live on campus. At the 0.05 level of significance, is there
sufficient evidence to support the claim that a difference exists
between the proportions of male and female students who live on
campus?

A random sample of 200 students was drawn from a large
university. It was found that 73 students in this sample live in
off-campus apartment. Construct a 90% confidence interval for the
proportion of students in this university that live in off-campus
apartment. Use normal approximation in this question.
