The null hypothesis will be that the average annual donor income is less or equal to $ 100,000
Step-by-step explanation:
The claim is mostly treated as alternate hypothesis .
In this question the claim is given as the average annual donor income has increased therefore it is written as

H0: u ≤ 100,000
The null hypothesis will be that the average annual donor income is less or equal to $ 100,000
