MAparison of student's performance involved the total of n = 600 respondents. Two groups selected were: a majors and and Computer Science majors. Individual performance was measured in a binary scale (ABOVE or BELOVW average). The summaries are presented below. Group Size ABOVE Proportion MATH X1 = 140 (Đ)1 = 140/200 = 0.7 n1 = 200 COMP Science n2 = 400 X2 = 310 (p)2 = 310/400 = 0.775 Pooled n = nị + n2 = 600 X = X1 + X2 = 450 p = 450/600 = 0.75 At the significance level, a = 0.05, do you have sufficient evidence that population proportions DIFFER? • Evaluate the test statistic • Specify critical value (or values) needed for this procedure. • State the Rejection Rule • Formulate your decision Solution 9.
