question 8

Essay

Suppose that you wish to use a Wilcoxon signed-rank test to perform a hypothesis test for a population mean. If the absolute differences contain ties, how should you assign the ranks? For example if two absolute differences are tied for fourth place, what ranks should they receive? If three absolute differences are tied for eighth place, what ranks should they receive?
