Explanation:

Step1: Recall quartile concepts

The inter - quartile range (IQR) represents the middle 50% of the data. It is between $Q_1$ and $Q_3$. The bottom 25% of the data is less than $Q_1$ and the top 25% of the data is greater than $Q_3$.

Step2: Answer question 2

The middle 50% of school - aged children played video games between the first quartile ($Q_1$) and the third quartile ($Q_3$). Given $Q_1 = 3$ and $Q_3=12.5$, the values are 3 and 12.5.

Step3: Answer question 3

The bottom 25% of school - aged children played video games less than the first quartile ($Q_1$). So the value is 3.

Step4: Answer question 4

The top 25% of school - aged children played video games more than the third quartile ($Q_3$). So the value is 12.5.

Answer:

1. 3, 12.5
2. 3
3. 12.5
