Transcribed Image Text:An article estimated that 80 percent of students at a large public university who are Facebook users log into their Facebook profiles at least six times a day. Suppose that you plan to select a random sample of 400 students at your college. You will ask each student in the sample if he or she is a Facebook user and if they log into their Facebook profile at least six times a day. You plan to use the resulting data to decide if there is evidence that the proportion for your college is different from the proportion reported in the article for the other college. What hypotheses should you test? (Let p = the proportion of college students who are Facebook users and log into their Facebook profile at least six times a day.) Ho: p= 0.8 versus ₂: p = 0.2 a' ΟΗ o p = 0.8 versus H₂: p + 0.8 a OH o: P = 0.2 versus H a: P = 0.8 H o: P 0.8 versus H. a: P = 0.2 H o: P = 0.2 versus H₂:p # 0.2 a
