Test the claim about the difference between two population means , and 2 at the level of significance . Assume the samples are random and independent, and the populations are normally distributed. Claim: H1 = H2; 0 = 0.01 Population statistics: 61 = 3.2, 62 = 1.7 Sample statistics: x1 = 15, n1 = 30, X2 = 13, n2 = 29 Determine the alternative hypothesis. Ha : H1 H2 2
