Explanation / Answer

The output states that the null hypothesis is that GDP_growth rate has a unit root.

We notice that at all levels of significance the null hypothesis can be rejected since p-value < 0.01. Hence the null hypothesis can be rejected and the GDP_Growth_rate series is stationary as it doesn't have a unit root.
