While one can not "clear" a null hypothesis, one can tell how close it is to being genuinely with a power testwhich involves for type II errors. While the results of data analysis work best on track from randomized terrestrialsthey are also useful to other sources of data—like natural experiments and organized studies  —for which a statistician would use a bit, more structured estimation garden e.
