Step-by-step solution

Given information

An average worker in Germany gets $8$weeks of paid vacation.

Calculation

Now solving,

Assuming average worker paid vacation as $\mu .$\mu.

The null and alternative hypothesis are obtained as as :

$$\begin{gathered} {\mathrm{H}}_0:\mu =8 \\ {\mathrm{H}}_{\mathrm{a}}:\mu \ne 8 \end{gathered}$$

This shows that this hypothesis test is for single mean.

Final answer

The hypothesis test is for single mean.
