The mean length of the fish.

The mean is calculated as,

[tex]\begin{gathered} Mean\text{ =}\frac{\sum^xf}{\sum^f} \\ =\frac{5\times3+6\times1+7\times1+8\times2+9\times3+10\times4+11\times6+12\times1}{21} \\ =\frac{15+6+7+16+27+40+66+12}{21} \\ =\frac{189}{21} \\ =9 \end{gathered}[/tex]

Hence, the mean length is 9.
