Answer 2

Answer:

The correct answer is Option 4 : $40$

Explanation:

Range $= L-S$

Where $L$ is the largest value and $S$ is the smallest value.

Here, $L=-4$ and $S=-44$

Hence, range $=(-4)-(-44)$

$=40$

Therefore the range of these observations is $40$.

Range : The range of a given set of observations is the difference between the highest and lowest values.

While considering the largest and smallest values, sign of the values are also to be noted.
