Explanation:

In hypothesis testing, the null hypothesis ($H_0$) is formulated to represent a state of no - effect, no - difference, or no - change. For example, in a test comparing the means of two populations ($\mu_1$ and $\mu_2$), the null hypothesis would be $H_0:\mu_1=\mu_2$ (suggesting no difference between the population means).
