Hypothesis testing
Hypothesis testing is used to test if a conclusion is valid for a specific data set by comparing the data against a certain assumption. The result of the test can nullify the hypothesis, where it is called the null hypothesis or hypothesis 0. Anything that violates the null hypothesis is called the first hypothesis or hypothesis 1.
Example: From the regression calculation above, you want to test the hypothesis that mileage affects the maintenance costs of a car. To test the hypothesis, you claim mileage affects the maintenance costs of a car. Here, we reject the null hypothesis since the regression above shows that mileage influences car maintenance costs.
