Justification:

Here, the claim is that the median tenure for workers from the representative's district is less than the national median tenure of 4.6 years. In the given experiment, the alternative hypothesis indicates the claim.

The test hypotheses are given below:

Null hypothesis:

\(H_{0} : Median > 4.6years\)

That is, the median tenure for workers from the representative's district is not less than the national median tenure of 4.6 years.

Alternative hypothesis (Claim):

\(H_{a}, : Median < 4.6 years\)

That is, the median tenure for workers from the representative's district is less than the national median tenure of 4.6 years.
