The video attempts to explain the application of statistical hypothesis testing to real life scenarios. Whilst doing so, it also aims to clarify some misconceptions about using statistical tests.

It tries to provide a correct perspective on utilizing the correct statistical hypothesis test specific to a scenario. This results in a more useful understanding of the concept of statistical hypothesis testing applicable to a real-life situation.

In addition to the above, the video also clarifies the concept and the process of statistical hypothesis testing. To simply use the formulae used in statistical hypothesis testing, a bonus tip has also been shared in the video for doing the calculations.
