Two random samples are taken, one from among first-year students and the other from among fourth-year students at a public university. Both samples are asked if they favor modifying the student Honor Code. A summary of the sample sizes and number of each group answering yes" are given below: n = 85, x = 35 Fourth-Years (Pop. 2): n2 = 98, x2 = 53 First-Years (Pop. 1): Is there evidence, at an a = 0.02 level of significance, to conclude that there is a difference in proportions between first-years and fourth-years? Cary out an appropriate hypothesis test, filling in the information requested. A. The value of the standardized test statistic: Note: For the next part, your answer should use interval notation. An answer of the form (-0o, a) is expressed (- infty, a), an answer of the form (b, 0) is expressed (b, infty), and an answer of the form (-o, a) U (b, co) is expressed (-infty, a)U(b, infty). B. The rejection region for the standardized test statistic: C. The p-value is D. Your decision for the hypothesis test: A. Do Not Reject H. B. Do Not Reject Ho. C. Reject Ho. D. Reject H.
