Another question for ya guys.... If someone can help to summarize approaching hypothesis testing? I have trouble when to incorporate sampling error or standard error, and when to reject the null and when to fail to reject. I know this is broad but if anyone has a good way to summarize this and explain how to approach these types of problems and how to know to rreject etc, I would greatly appreciate it. This is just a topic that continually gives me problems. Thanks so much guys
