Solution

The correct option is C
BATMAN, 3

$A v e r a g e = \frac{S u m o f a l l o b s e r v a t i o n s}{T o t a l n u m b e r o f o b s e r v a t i o n s}$

Here, for both the cases, the total number of observations is the same and it is 7.

Average number of villians caught by Batman per day = $\frac{2 + 5 + 4 + 1 + 3 + 2 + 4}{7}$ = $\frac{21}{7}$ = 3.

Average number of villians caught by Superman per day = $\frac{3 + 4 + 2 + 2 + 1 + 2 + 0}{7}$ = $\frac{14}{7}$ = 2.

So, BATMAN's average is higher and it is 3.
