You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. Ho: H1 H2 50 Ha Ha H20 The following results are for two independent samples taken from two populations. Sample 1 Sample 2 Sample Size 38 34 Sample Mean 42 36 Sample Variance 142 171 (a) Determine the degrees of freedom for the t-distribution. (Use Sample 1 Sample 2. Round your answer down to the nearest integer.) 78 X (b) Compute the test statistic. (Round your answer to three decimal places.) 1.719 x (c) Determine the p-value. (Round your answer to four decimal places.) (d) Test the above hypotheses. Let a = 0.05. Reject Ho. There is sufficient evidence to conclude that > 0. Do not reject Ho. There is insufficient evidence to conclude that > 0. Reject Ho. There is insufficient evidence to conclude that > 0. - Do not reject Ho. There is sufficient evidence to conclude that > 0.
