    \end{aligned}
\end{equation*}
\begin{equation*}
\begin{aligned}

有很多方法可以获取一个简单的盒子，例如framed包装和环境。（对于更精美的东西，请查看tcolorbox或。）我根本不会为此mdframed使用。equation*

\documentclass{article}
\usepackage{framed}
\begin{document}
\begin{framed}
\noindent $H_0$: There is no association between the number of seasons a club has previously played in the top  division and survival
\end{framed}
\begin{framed}
\noindent $H_1$: There is an association between the number of seasons a club has previously played in the top  division and survival
\end{framed}
\end{document}
