Solution

The correct option is B False
Finding the mean:
As we know that ,
Mean $= \frac{s u m o f o b s e r v a t i o n}{n u m b e r o f o b s e r v a t i o n}$
Therefore we have
Mean $= \frac{6 + 4 + 3 + 8 + 9 + 12 + 13 + 9}{8}$
$= \frac{64}{8} = 8$
So, the mean of the given data is $9$
Hence, the given statement is false.
