You are comparing the means of two unrelated samples, A dan B. You have the following information: L'A = 16, s = 4, nA = 14 XB = 14, s3 = 3, ng = 12 (a) What is the degree of freedom if we assume equal variances? (b) What is the degree of freedom if we assume unequal variances? (c) What is the test statistics if we assume unequal variances and that the mean difference is equal to zero?
