- What is the interpretation of the results from the Wilcoxon Signed-Ranks Test?A researcher wants to compare the effectiveness of two treatments on a sample of 25 patients. What is the null hypothesis for the Wilcoxon Signed-Ranks Test?When should the Wilcoxon Signed-Rank test be used instead of a paired t-test?
- What is the null hypothesis in the Wilcoxon Signed-Ranks Test?If the Durbin-Watson statistic is greater than (4 − dL), then we conclude that there is significant positive autocorrelation. there is significant negative autocorrelation. there is significant autocorrelation, but we cannot identify whether it is positive or negative. the test result is inconclusive.A recent study of 100 individuals found the following living arrangements for men and women. Can it be concluded that there is a dependent relationship between gender and living arrangements at the α = 0.025 level of significance. Use the chi-square test of independence.
