Test the claim about the difference between two population means , and 2 at the level of significance o. Assume the samples are random and independent, and the populations are normally distributed. Claim: H1 = H2; @ = 0.01 Population statistics: 61 = 3.5, 62 = 1.5 Sample statistics: X, = 16, n, = 31, X2 = 18, n2 = 30 Determine the alternative hypothesis. Ha: My # H2
