> **Disclaimer: I have no idea what your data represents or how
(in)appropriate any of these tests may be**
R can do the tests you mentioned (and many more).
Wilcoxon test:
wilcox.test(x=group1, y=group2, paired=FALSE)
see ?wilcox.test
I am not sure whether it is still valid but in case of ties (equal
values in the same group) like in your example data you should use the
wilcox_test from the coin package. That one has a correction for ties.
But as Joshua told correctly as far as we do not know your data, Linda,
it is hard to tell what might be approproate...
