7. An instructor wants to claim for students "po% of my students would take a class with me again". On the site www.ratemyprofessors.com (http://www.ratemyprofessors.com)_he has found that only 47.4% would take a class with him again (27 out of 57 ratings). Of course, he does not want to announce that most students said "no", but he does not want to lie also. He has decided to make a claim that would not be rejected at a 5% significance level if this sample data were used. What is the best claim which he can make? Hypotheses: Ho: p = p0% Ha: p
