The null hypothesis states that any effects observed after treatment (or associated with a predictor variable) are due to chance alone. Statistically, the question that is being answered is If these samples came from the same population with regard to the outcome, how likely is the obtained result?
If you fail to reject the null hypothesis then you have observed a sample that is plausible assuming the null is true. the conclusion is that the null is plausible. you cannot conclude the null is true. Consider the hypothesis as a trial against the null hypothesis. the data is evidence against the mean.
