Given sample sizes n1 = n2 = 10, sample means = 5.2 and =7.1, and sample variances = 4 and = 6.2 using alpha = 0.05, test the hypothesis H0: u1 = u2 against Ha: u1 does not equal u2. A) What assumptions do we need to make about the data to use the central limit theorem? B) What is the value of the appropriate test statisctics?
