The alternative hypothesis (H A) represents an alternative claim under consideration and is often represented by a range of possible parameter values.Even if we fail to reject the null hypothesis, we typically do not accept the null hypothesis as true. Failing to find strong evidence for the alternative hypothesis is not equivalent to accepting ...
