You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. Ho: #11₂50 H₂H₁-H₂>0 The following results are for two independent samples taken from the two populations. Sample 1 01-40 X₁25.8 %1 = 5.2 Sample 2 ₂ = 50 X₂= 22.8 %₂56 (a) What is the value of the test statistic? (Round your answer to two decimal places.) 2.12 x (b) What is the p-value? (Round your answer to four decimal places.) 0.0172 x (c) With a = 0.05, what is your hypothesis testing conclusion? Reject Ho. There is insufficient evidence to conclude that #₁ - H₂> 0. Do not Reject Ho: There is sufficient evidence to conclude that H₁-H₂> 0. Do not reject Ho There is insufficient evidence to conclude that #₁ - H₂> 0. Reject Ho. There is sufficient evidence to conclude that #₁H₂> 0.
