Solution Summary

The expert examines independent test or dependent tests on population means.

Solution Preview

Let me first start by saying that dependent test is for within subject design. This is when the same subjects are used in more then one treatment. For example, you would have a person undergo two different treatments and compare the results within each other.

Independent test is for between subject design. Between subject design is when the subject only participants once in the study. Here, you would compare the results of people against other people.

So in 2 sample z-test, we compare ...
