Hypothesis testing is the cornerstone of statistical analysis and the scientific method. If you are doing research or analyzing data, then you might be wanting to use statistics to draw your conclusions.

Statistical tests provide a p-value and a 95% confidence interval that can be used to accept or reject a null hypothesis.
