State hypotheses for the significance test. Last year, the results of a survey at one college suggested that 28% of students smoked regularly. This year, after an intensive college-wide anti-smoking campaign, a researcher wishes to investigate whether the proportion of smokers has changed. Let p represent the p students who smoke regularly today. State hypotheses for a significance test, letting the alternative hypothesis reflect the possibility that the proportion of students who smoke today is different from the proportion last year. Ho: p= 28% Ha: p 28 % Ho:p> 28% Ha: p < 28% Ho: p= 28% H₂: p2 28% Ho: P * 28% H₂:p=28%
