Consider the following hypothesis test. но: 1-250 H₂H₁-H₂> 0 The following results are for two independent samples taken from two populations. Sample 1 Sample Size Sample Mean Sample Variance 142 (a) Determine the degrees of freedom for the t-distribution. (Use Sample 1 - Sample 2. Round your answer down to the nearest integer.) 31 39 Sample 2 28 (d) Test the above hypotheses. Let a = 0.05. 32 172 (b) Compute the test statistic. (Round your answer to three decimal places.) (c) Determine the p-value. (Round your answer to four decimal places.) O Reject Ho. There is sufficient evidence to conclude that μ₁ - ₂ > 0. O Do not reject Ho. There is sufficient evidence to conclude that ₁ - ₂ > 0. O Do not reject Ho. There is insufficient evidence to conclude that μ₁ −μ₂ > 0. O Reject Ho. There is insufficient evidence to conclude that μ₁ - ₂ > 0.
