\item Like this,
\item and like this.
\end{enumerate}

\dots or bullet points \dots

\begin{itemize}
\item Like this,

\subsection{Model}

Let $X_1, X_2, \ldots, X_n$ be a sequence of independent and identically distributed random variables with $\text{E}[X_i] = \mu$ and $\text{Var}[X_i] = \sigma^2 < \infty$, and let

\[S_n = \frac{X_1 + X_2 + \cdots + X_n}{n}
      = \frac{1}{n}\sum_{i}^{n} X_i\]
      
atau dibuat 2 baris

\begin{equation}

\begin{align}
S_n &= \frac{X_1 + X_2 + \cdots + X_n}{n} \\
    &= \frac{1}{n}\sum_{i}^{n} X_i
\end{align}
\end{equation}

denote their mean. Then as $n$ approaches infinity, the random variables $\sqrt{n}(S_n - \mu)$ converge in distribution to a normal $\mathcal{N}(0, \sigma^2)$.
