Simple code (new to LaTeX). Receiving these errors:
Underfull \hbox (badness 10000) in paragraph at lines 13--14
Underfull \hbox (badness 10000) in paragraph at lines 15--26
Underfull \hbox (badness 10000) in paragraph at lines 15--26
Underfull \hbox (badness 10000) in paragraph at lines 15--26
Underfull \hbox (badness 10000) in paragraph at lines 27--28
Here is code
\documentclass[11pt]{article}

\textbf{2.3 Suppose that the values for a given set of data are grouped into intervals. The intervals and corresponding frequencies are as follows:} \\
\indent
\begin{tabular}
{|l r|} \hline
age & frequency \\ \hline
1-5 & 200 \\
6-15 & 450 \\
16-20 & 300 \\
21-50 & 1500 \\
51-80 & 700 \\
81-110 & 44 \\ \hline
\end{tabular} \\ \\ \\
\textbf{Compute an \textit{approximate median} value for the data.}\\
My answer here.
\end{document}
The line numbers are pointing to the 2 sections where i used \textbf and the other is pointing to the start/end of the tabular.
What is wrong with the code?
