Suppose we wish to test H0: μ1 - μ2 ≤ 0 versus HA: μ1 - μ2> 0. Independent random samples are taken from two normally distributed populations with unknown variances. The following sample statistics are given: X¯11 = 15.4, X¯2 = 14.5, s1 = 2, s2 = 2.28, n1 = 35, n2 = 18. Assuming that the population variances are not equal, what is the value of the appropriate test statistic?
