@Kuba brevity as per accepted answer in mathematica.stackexchange.com/questions/31152/… but yes on OS X the syntax coloring prior to evaluation indicates non-standard usage so yes "None" is probably better -otoh maybe a latent wish that without either (i.e. single argument) would syntactically suffice since the pattern shouldn't interfere with other option usages?

no syntax error on V9.0 on OS X. Does Grid[{{1, 2}, {3, 4}}, ItemStyle -> {None, None, {{1, 1} -> Directive[30]}}, Background -> {None,None, {{1, 1} -> Red}}, Frame -> All] go through?

Yes I similarly overlooked this point and it does seem to confirm that this significance level is being inherited from the original invocation.

Yes but one might have expected that there is an outcome of the variance check that results in "SignedRank" still being chosen. I.e. otherwise we are moving into Heisenberg territory in which the mere process of "checking" equal variances becomes pivotal (given NHST's dichotomous tradition of being either true or false). At any rate, I agree this is a red herring since there is only one sample. Perhaps what is going on ... see addition to question

Yes, and curiously LocationTest[sample, Automatic, "AutomaticTest", SignificanceLevel -> 0.05, VerifyTestAssumptions -> #] & /@ {"Normality", "EqualVariance", "EqualVariance" -> True, "EqualVariance" -> False} gives {"SignedRank", "T", "T", "T"} but in this example there is only one sample so I'm not sure what variances are being checked for equality?
