Bug: Wilcoxon rank sum test in Prism 6

The Wilcoxon signed rank test is part of the column statistics analysis. You check the option to compare the median with a theoretical value, and ask for a nonparametric test. 

Prism 6.02 and 6.0c introduced an awful bug. The Wilcoxon signed rank test always reported P<0.0001. This bug was not in 6.00, 6.0a, 6.01, or 6.0b, and is fixed in 6.03 and 6.0d. 

The related Wilcoxon matched-pairs test is fine. This bug is only in the signed rank test that is part of column statistics.
