Please help me I do not understand. Thank you in advance!





Information v Flag question Mann-Whitney Test Independent random samples were selected from two populations, Population A and Population B. The samples are provided in the tables below. Table A: Sample from Population A 115.7 105.7 103.0 85.3 96.1 95.5 88.0 87.7 96.2 96.0 87.0 104.4 114.0 100.0 Table B: Sample from Population B 109.2 116.7 105.6 105.4 130.6 101.4 97.9 112.6 116.0 99.8 127.5 92.7 Is there sufficient evidence, at the o = 0.025 level of significance, to conclude that Population B is shifted to the right of Population A? Use the Mann-Whitney Test to answer this question. Notes: 1. Use the exact test. 2. Be sure to use the same type of "1-2" sample & population relabeling that was used in the lectures. Some of the answers will be based on that relabeling. Mann-Whitney Test Select the appropriate hypotheses to answer this question. Select one: Ho : Population 1 = Population 2 VS H1 : Population 1 * Population 2 Ho : Population 1 = Population 2 vS H1 : Population 1 Population 2 Question 23 ot yet answered Points out of 5.00 Flag question Mann-Whitney Test Determine the critical point for the test.

Answer: Juestion 29 ot yet answered Points out of 5.00 v Flag guestion Mann-Whitney Test What is the conclusion at the o = 0.025 level of significance? Select one: O There is sufficient evidence to conclude that the populations differ in terms of location O There is insufficient evidence to conclude that Population 1 is shifted to the left of Population 2 O There is insufficient evidence to conclude that Population 1 is shifted to the right of Population 2 O There is sufficient evidence to conclude that Population 1 is shifted to the right of Population 2 O There is insufficient evidence to conclude that the populations differ in terms of location O There is sufficient evidence to conclude that Population 1 is shifted to the left of Population 2
