Detailed explanation-1: -Statistical/Null Hypothesis (H0): A null hypothesis proposes or predicts that there is zero difference or no difference between the parameter and its assumed value.
Detailed explanation-2: -What is the Null Hypothesis? The null hypothesis states that there is no relationship between two population parameters, i.e., an independent variable and a dependent variable. If the hypothesis shows a relationship between the two parameters, the outcome could be due to an experimental or sampling error.
Detailed explanation-3: -Statement of zero or no change. If the original claim includes equality (<=, =, or >=), it is the null hypothesis. If the original claim does not include equality (<, not equal, >) then the null hypothesis is the complement of the original claim. The null hypothesis always includes the equal sign.
