Suppose you want to take a random sampie of GMAT scores to determine whether there is a significant difference between the GMAT scores given in March and the scores for the test given in June. Use the Mann Whitney U-test to determine whether there is a significant difference in the two test results at a 10% significance level. March: 540, 740, 600, 430, 500, 510, 530, 560, 550, 490 June: 350, 470, 630, 590, 610, 520, 460, 550, 530, 57o Let June be group 1. What is the rank sum, W1? What is the value of the test statistic, UP What is the decision and conclusion for the test at a 10% significance level? O Reject Ho. There is a difference in GMAT scores betveen March and June. O Reject Ho. There is no difference in GMAT scores between March and June. O Fail to Reject Ho. There is no difference in GMAT scores between March and June. O Fail to Reject Ho.
