I'm trying to estimate the p-value range for a Wilcoxon Signed-Rank Test using a "www.dekasinthevents.org/images/wtable.jpg" [Broken]. For example: Ho: M1 = M2 Ha: M1 < M2 alpha = 0.05 n = 17 I calculated W = 62 and the rejection region W <= 41. So I would reject Ho. But I'm also required to know how to come to a conclusion using the estimated p-value that's supposed to come from the "www.dekasinthevents.org/images/wtable.jpg" [Broken]. In a t-test using a t-table I would look at the t-table at the row with the right degrees of freedom and see where my test statistic would fall in. When I try to do this with a Wilcoxon test and a W-alpha table it gives me conclusion that contradicts the one I get from the test itself. Any ideas on how to estimate the p-value properly from the W-alpha table? Thanks.
