ANS:
A null hypothesis permits researchers to assess whether an apparent relationship is genuine or is likely to be a function of chance. If statistical tests indicate that the observed relationship has only a very slight probability of occurring by chance, then we can reject the null in favor of the alternate hypothesis.
