experimental results show that the null hypothesis may be mistaken, and thus, in this case, it is discarded and replaced the hypothesis development and testing. In the case of a hypothesis that is not refuted by the results, it may form the basis for the theory to explain this phenomenon. Experimental science has placed the importance of the publication, they may be re-created by other researchers to prove the consistency of the rights of observation so that they might further refine the…
