Independent random samples selected from two normal populations produced the sample means and standard deviations shown to the right. Assuming equal variances, conduct the test Ho: (H1 -H2) =0 against H,: (H1 -H2) #0 using a = 0.10. Sample 1 Sample 2 n, = 17 n2 = 13 X1 = 5.3 X2 = 7.6 s, = 3.9 s2 = 4.7 Find the test statistic. The test statistic is (Round to two decimal places as needed.) Find the p-value. The p-value is. (Round to three decimal places as needed.) State the conclusion. Choose the correct answer below. O A. Do not reject Ho. There is insufficient evidence that the means differ. O B. Do not reject Hn. There is sufficient evidence that the means differ. O C. Reject Ho. There is sufficient evidence that the means differ. O D. Reject Ho. There is insufficient evidence that the means differ.
