## What is central limit theorem?

The Central Limit Theorem in statistics states that the population means will be the average of your sample means. Plausibly, add the averages of all of your samples together and calculate the average, which the population means.

Central Limit Theorem can also be defined in terms of the calculus limit.

The CDF of the standard sample mean is given by Sample Mean which will converge at a point $\varnothing \left(z\right)$

$Thus:li{m}_{n\underset{}{\to}\infty}P\left(\frac{\overline{{X}_{n}}-\mu}{\delta}\right)\le z=\varnothing \left(z\right)$

where ${X}_{n}$ is the ID sequence

The calculus definition has an assumption that the expected value of X and X^2 are less than infinity.
