You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. Ho: M 1 - M2 so Ha: M 1 - M2 > 0 The following results are for two independent samples taken from two populations. Sample 1 Sample 2 Sample Size 36 33 Sample Mean 48 42 Sample Variance 135 166 (a) Determine the degrees of freedom for the t-distribution. (Use Sample 1 - Sample 2. Round your answer down to the nearest integer. ) (b) Compute the test statistic. (Round your answer to three decimal places.) (c) Determine the p-value. (Round your answer to four decimal places.) (d) Test the above hypotheses. Let a = 0.05. O Do not reject Ho. There is insufficient evidence to conclude that M1 - M2 > 0. O Reject Ho. There is insufficient evidence to conclude that M1 - M2 > 0. O Do not reject Ho. There is sufficient evidence to conclude that M, - M2 > 0. O Reject H . There is sufficient evidence to conclude that u, - M2 > 0
