Calculate the mean from a frequency table This table shows the number of pets a group of students owns.
If calculating the mean number of pets owned, what would replace the star? \begin{tabular}{|c|c|c|}
\hline Number of pets & Frequency & \\
\hline \( 0 \) & \( 9 \) & \\
\hline \( 1 \) & \( 5 \) & \\
\hline \( 2 \) & \( 4 \) & \( \color{gold}\bigstar \)
\hline \( 3 \) & \( 2 \) & \\
\hline \( 4 \) & \( 3 \) & \\
\hline
\end{tabular} \( 2+4=6 \)
