Test the claim about the difference between two population means u, and µ2 at the level of significance a. Assume the samples are random and independent, and the populations are normally distributed. Claim: 41 = H2; a = 0.01 Population statistics: 6, = 3.4, o2 = 1.5 Sample statistics: x = 14, n, = 31, x2 = 12, n2 = 26 ..... Determine the alternative hypothesis. Hai H1 H2 Determine the standardized test statistic. | (Round to two decimal places as needed.) Determine the P-value. P-value =D (Round to three decimal places as needed.) What is the proper decision? O A. Reject Ho. There is not enough evidence at the 1% level of significance to reject the claim. O B. Fail to reject Ho. There is not enough evidence at the 1% level of significance to reject the claim. OC. Fail to reject Ho. There is enough evidence at the 1% level of significance to reject the claim. O D. Reject Ho. There is enough evidence at the 1% level of significance to reject the claim.
