Use the Wilcoxon matched-pairs signed-ranks test to test the given hypotheses at the α=0.05 level of significance. The dependent samples were obtained randomly. H0: MD=0 versus H1: MD>0 with n=17 and T−=−48
Part 1
What is the conclusion of the hypothesis test?
A.Since the test statistic is less than the critical value, reject the null hypothesis H0: MD=0.
B.Since the test statistic is greater than the critical value, reject the null hypothesis H0: MD=0.
C.Since the test statistic is less than the critical value, do not reject the null hypothesis H0: MD=0.
D.Since the test statistic is greater than the critical value, do not reject the null hypothesis
Part 2
Use the Wilcoxon matched-pairs signed-ranks test to test the given hypotheses at the α=0.05 level of significance. The dependent samples were obtained randomly. Hypotheses: H0: MD=0 versus H1: MD≠0 with n=23, T−=50 and T+=73.
Is there any significant evidence that the the alternative hypothesis is true?
A. Yes comma it is significant. The test statistic is less than the critical value.
Yes, it is significant. The test statistic is less than the critical value.
B. Yes, it is significant. The test statistic is greater than or equal to the critical value.
C. No comma it is not significant. The test statistic is greater than or equal to the critical value.
No, it is not significant. The test statistic is greater than or equal to the critical value.
D. No, it is not significant. The test statistic is less than the critical value.
