Solution

The correct option is C 3
You know,
$M e a n = \frac{S u m o f t h e o b s e r v a t i o n s}{N u m b e r o f t h e o b s e r v a t i o n s}$

The numbers are given as $1, 2, 3, 5$ and $6$ .

So, mean $= \frac{1 + 2 + 3 + 5 + 6}{5}$
$= \frac{17}{5}$

$= \frac{17 \times 2}{5 \times 2}$

$= \frac{34}{10}$ $= 3.4$

Estimating 3.4 to the nearest whole number, you get 3.

Therefore, the mean of the given numbers estimated to the nearest whole number is 3.
