Test the claim about the difference between two population means Hy and H2 at the level of significance a. Assume the samples are random and independent, and the populations are normally distributed. Claim: My SM2; a=0.01. Assume 02 +02 Sample statistics: x1 = 2400, s, = 174, n, = 12 and x2 =2303, S2 = 54, n2 = 10 . Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho H1 H2 Ha: H15H2 B. HOH SH2 H:H1 H2 OD. HOE H2H2 Ha: H2 C. Ho H1 =12 H:H * H2 O E HO H1 H2 H:H1212 OF HOH + H2 H:H7 = H2 Find the standardized test statistic t. (Round to two decimal places as needed.)
