Detailed explanation-1: -The hypothesis actually to be tested is usually given the symbol H0, and is commonly referred to as the null hypothesis. As is explained more below, the null hypothesis is assumed to be true unless there is strong evidence to the contrary – similar to how a person is assumed to be innocent until proven guilty.
Detailed explanation-2: -What Is a Null Hypothesis? A null hypothesis is a type of statistical hypothesis that proposes that no statistical significance exists in a set of given observations. Hypothesis testing is used to assess the credibility of a hypothesis by using sample data.
