At a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the
school's reports, 39% 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,
54 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 39%.

(b) For your hypothesis test, you will use a Z-test. Find the values of np and n (1-p) to confirm that a Z-test can be
used. (One standard is that np≥ 10 and n (1-p)≥10 under the assumption that the null hypothesis is true.) Heren is
the sample size and p is the population proportion you are testing.

(d) Based on your answer to part (c), choose what can be concluded, at the 0.10 level of
significance, about the claim made in the school's reports.
Since the p-value is less than (or equal to) the level of significance, the null hypothesis is
rejected. So, there is enough evidence to reject the claim that 39% of students will find a
