recent study by Munro et al found that 15% of college freshman were not happy with their choice of major. A random sample of 100 college juniors found that 10% were not happy with their major. Is there sufficient evidence to suggest that the proportion of students not happy with their major is smaller among juniors than a freshman? Use alpha = .05. I.State the hypotheses. II.Calculate the test statistic. III.Find the p-value. IV.Make a statistical decision. V.State your conclusion in the context of the problem.
