Hypothesis Testing - Z test & T test

Описание к видео Hypothesis Testing - Z test & T test

In this video we solve some hypothesis testing problems using both the z test and t test. It involves one-tail and two-tail tests.

We look at when to use the z test and when to use the t test. We then apply our learning to some exercises. They involve stating the null and alternative hypothesis, calculating the critical value, calculating the z/t value and finally determining whether we reject or accept the null hypothesis.
