Answer 2

Answer:

The correct answer is Option A : $55$

Step-by-step explanation:

First, we have to arrange the observation in ascending order.

We get : $32,39,39,45,70,77,93,94,104,109$

Now, find the median :

Median $Q_2=\frac{70+77}{2}$

$Q_2=73.5$

The median of the numbers which are to the left of $Q_2$ : $Q_1=39$

The median of the numbers which are to the right of $Q_2$ : $Q_3=94$

Inter quartile range $=Q_3-Q_1$

$=94-39\\=55$

Therefore the answer is $55$.
