Question

A random sample of 10 students was selected at Excelsior University for a study of how students change the way they spend their out-of-class time from junior to senior year. As part of the study, when the students in the sample were in their junior year they were asked to estimate how much time they spent on social media like Facebook, Twitter, etc., on a typical class night. An identical question was asked of the same 10 students in their senior year. The table below shows the responses. Assuming that the necessary population conditions are satisfied, conduct a hypothesis test to test the hypothesis that the average time spent on social media by students at the university is unchanged from junior to senior year. Use a significance level of .05.
