\begin{array}{l}
41, 24, 26, 35, 25, 23, 24, 24, 50, 41, 25, 33, 21, 25, 31, \\
39, 37, 27, 33, 26, 27, 36, 20, 36, 42, 40, 45, 29, 27, 38 \\
\end{array}

Complete the frequency table that could be used to create a histogram representing the given data set.

\begin{tabular}{|c|c|c|c|c|}
\hline
Interval & [tex]$20-28$[/tex] & [tex]$28-36$[/tex] & [tex]$36-44$[/tex] & [tex]$44-52$[/tex] \\

To complete the frequency table, let’s tally the number of ages that fall within each specified interval based on the given data set.

\begin{tabular}{|c|c|c|c|c|}
\hline Interval & [tex]$20-28$[/tex] & [tex]$28-36$[/tex] & [tex]$36-44$[/tex] & [tex]$44-52$[/tex] \\
\hline Frequency & [tex]$14$[/tex] & [tex]$7$[/tex] & [tex]$7$[/tex] & [tex]$2$[/tex] \\
\hline
\end{tabular}

Hence, the frequency table is:
- For the interval 20-28, the frequency is 14.
- For the interval 28-36, the frequency is 7.
- For the interval 36-44, the frequency is 7.
- For the interval 44-52, the frequency is 2.
