Two key concepts in hypothesis testing are the null and the alternative hypothesis. Formulating the hypothesis test in the right manner, i.e. by correctly formulating null and alternative hypothesis is the first step towards solving the problems in the right manner.
How do we represent these concepts tl (i.e. what abbreviation we use to denote null and alternative hypothesis)?
