  A study was conducted to determine whether students would benefit from a new method of exam review. The table below shows data of those who passed their next exam. Treat the students who used the Traditional Method as Group 1 and the New Method as Group 2. At α = 0.025, test whether a lower proportion of students using the Traditional Method passed compared with those students using the New Method. Traditional New x1 = 320 x2 = 74 n1 = 400 n2 = 100   Compute the test statistic. Report your answer to 3 decimal places. (Be careful with your signs!)
