Discuss why we would expand the idea of hypothesis testing to two populations. Can you provide an example of this type of hypothesis testing?

Solution

We may epand the idea of hypothesis testing of two population so that we can relate the characteristics features of the two population are same or not and to find the common features of the two population. Eg the hypothesis to check wether the mean height of the stes are same or not.
