Solution

The correct option is C 5
You know,
$M e a n = \frac{S u m o f t h e o b s e r v a t i o n s}{N u m b e r o f t h e o b s e r v a t i o n s}$

Putting the values from the dot plot,

$M e a n = \frac{2 + 4 + 4 + 7 + 7}{5}$
$= \frac{24}{5}$

$= \frac{24 \times 2}{5 \times 2}$

$= \frac{48}{10}$ $= 4.8$

Estimating 4.8 to the nearest ones, you get 5.

Therefore, the mean of the given data represented through dot plot estimated to the ones place is 5.
