Which is an example of statistical hypothesis testing?
Now that we understand the general idea of how statistical hypothesis testing works, let’s go back to each of the steps and delve slightly deeper, getting more details and learning some terminology.

Do you draw conclusions based on hypothesis testing?
In the case of hypothesis testing, based on the data, you draw conclusions about whether or not there is enough evidence to reject Ho. There is, however, one detail that we would like to add here.

What happens when you test an alternate hypothesis?
Your Alternate Hypothesis says that your new website actually is great and it really increased your customers. We first assume that our null hypothesis is true. So if you succeed in proving that your null hypothesis is false, you actually prove your alternate hypothesis to be true!
