Solve first 2 photos then for C it says Based on your answer to part C chose what can be concluded at the 0.05 levels of significance about the claim made in the school reports.
At a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the school's reports, 35% 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 170 students who visited the site looking for a roommate. Of the students surveyed, 64 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 0.05 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 35%. (a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test. Ho: 0 ロ<ロ OSO H;: 0 ロ=ロ ロロ (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 np210 and n(1-p) z 10 under the assumption that the null hypothesis is true.) Here n is the sample size and p is the population proportion you are testing. np= ] n (1-p)=D (c) Perform a Z-test. Here is some information to help you with your Z-test. Z0025 is the value that cuts off an area of 0.025 in the right tail of the distribution. Check Save For Later Submit As 2021 McGraw-Hill Education. All Rights Reserved. Terms of Use Privacy
