Lasciate ogne speranza, voi ch'intrate

Lasciate ogne speranza, voi ch'intrate", or "Abandon all hope, ye who enter here." It is, literally, what happen to those that uses NHST: they never get if the Null Hypothesis or the Alternative is true. The Dante´s Hell Gate.
. . . and the first obstacle arises to the newcomer: all mechanic starts supposing the Null Hypothesis true in order to derive a methodology to show if there is sufficient evidence - I prefer symptoms - the data is conformable with H0.
If he intends to know what its probability is he must to direct to Bayesian Probability.
By the other hand, in Classical theory, when we set, by hypothesis, that a parameter Teta is equal to g0, H0: Teta= g0, it should be clear that what we are willing to search is merely if DATA IS NOT ENABLE TO PROVIDE SUFFICIENT EVIDENCE THAT THE PARAMETER Teta HAS THE VALUE g0 . . . the rejection.
