No explanations needed, only correct solutions, thank you:

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: H1 = H2; a = 0.01 Population statistics: o, = 3.4, o, = 1.7 Sample statistics: X1 = 15, n, = 31, x2 = 13, n2 = 26 Determine the alternative hypothesis. Ha: H1 * H2 Determine the standardized test statistic. z= (Round to two decimal places as needed.)
