What is hypothesis testing?

Hypothesis testing is the statistical method that uses the data from a sample to conclude a population parameter or a population distribution.

There are two types of hypothesis testing. They are the null hypothesis and the alternative hypothesis.

If the obtained value is less than the threshold value then the null hypothesis is accepted and the alternative hypothesis is rejected.

If the obtained value is greater than the threshold value then the null hypothesis is rejected and the alternative hypothesis is accepted.
