[Tex/LaTex] Creating a Signature Line

formatting

I would like to create a signature line shown in the picture. Could you please help me?

Unfortunately I have used a table and I hope that I have helped you, also.

\documentclass{article}

\begin{document}

\begin{tabular}{@{}p{.5in}p{4in}@{}}
Approved: & \hrulefill \\
& Fats Domino, Ph.D. \\
& Chair of the Department of Nutrition\\
\end{tabular}

\end{document}
