Question
At a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the school's reports, 36% of students will find
a match their first time using the site. A writer for the school newspaper tests this claim by choosing a random sample of 160 students who visited the site
looking for a roommate. Of the students surveyed, 45 said they found a match their first time using the site.
Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to reject the claim that the
proportion, p, of all students who will find a match their first time using the site is 36%.
