Researchers collected data on the numbers of hospital admissions resulting from motor vehicle crashes, and results are given for Friday the 6th and Friday the 13th in the same month. Use the Wilcoxon signed-ranks test to test the claim that the matched pairs have differences that come from a population with median equal to zero at a significance level of a = 0.05. Fri. 6th 7 8 10 9 7 12 Fri. 13th 11 10 11 10 12 14 Click to view a table of critical values for the Wilcoxon signed-ranks test. First define the null and alternative hypotheses. Ho: Calculate the test statistic. T= Calculate the critical value. The critical value is What is the conclusion for this hypothesis test? OA. Fail to reject Ho. There is insufficient evidence to warrant rejection of the claim of no difference. OB. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim of no difference. OC. Reject Ho. There is insufficient evidence to warrant rejection of the claim of no difference. O D. Reject Ho. There is sufficient evidence to warrant rejection of the claim of no difference.
