So I am not sure when I am specifing p=0.05 we are taking

1) The prbability <0.05 :significant
1) The prbability <=0.05 :significant

The chance of p being EXACTLY .06 are infinitessimal, so it doesn't matter which of these it is.  I don't think I've ever seen it written up as <=, always <  but, as I said, it doesn't matter.
