Central Limit Theorem

[Tamara]

Is there an actual definition attached to the CLT? I’m confused on what it means and how/when to use it.

[DerekS]

If n>30 for a significance test or interval about means, then the sampling distribution of x bar is normal. This is how you satisfy the normality condition for a significance test about means.

Don’t forget the word “approximately” here.
