Hypothesis Testing

Introduction:

Let’s first try to understand what is Hypothesis testing from logic and give a verbal interpretation so as understand the main theme of this concept of Statistics which was first introduced by Ronald Fisher.  He presented this idea through a very famous example of Lady testing tea but, since, we are in 21st century we are going to explain this with a more recent example.

There is a scene in James Bond’ latest movie Spectre,  where he suggested that martinis should be shaken and not stirred. Since, he made the suggestion, we conducted an experiment with James Bond to know if he can really tell which martini’s drinks are shaken and which ones are stirred. So, we threw a coin and decided that if it comes head then we would stir the martini and if it is tails, then we would shake the martini without telling .
