What is the purpose of hypothesis testing in statistics?
What Is Hypothesis Testing? Hypothesis testing is an act in statistics whereby an analyst tests an assumption regarding a population parameter. The methodology employed by the analyst depends on the nature of the data used and the reason for the analysis. Hypothesis testing is used to assess the plausibility of a hypothesis by using sample data.
Which is the best software for hypothesis testing?
After identifying the test type, we can use different software packages to run the test. You can use Minitab, SPSS or R. Minitab is a popular application used for applied statistics and when we perform any statistical test, we get P-value as one of the output. Key concepts which will help you to interpret the test output:

Econometricians follow a formal process to test a hypothesis and determine whether it is to be rejected. The steps include: The first step involves positioning the null and alternative hypotheses. Remember, that these are mutually exclusive. If one hypothesis states a fact, the other must reject it.
