Before forming a hypothesis, researchers typically conduct background research to gather existing information related to their topic of interest. This involves reviewing literature, identifying gaps in knowledge, and understanding the context of the problem. Based on this understanding, they define a specific research question that guides the hypothesis formation.

How many types of errors in taking a decision about Ho?
There are two types of errors associated with hypothesis testing. Type I error occurs when the null hypothesis is rejected when it is true. Type II error occurs when the null hypothesis is not rejected when it is false. H0 is referred to as the null hypothesis and Ha (or H1) is referred to as the alternative hypothesis.

In other words, the null hypothesis must be the hypothesis you are almost sure of.
