Test the claim about the difference between two population means and 2 at the level of significance a. Assume the samples are random and independent, and the populations are normally distributed. Claim: = 2; = 0.01 Population parameters: o = 3.4, 02 = 1.5 Sample statistics: x = 17, n = 31, x2 = 19, n = 29 Determine the alternative hypothesis. Ha H H2
