I need a hypothesis for this question, I'm trying to understand this and what to write down: In the study of salamanders the researcher decided to further investigate the effect water quality had on the salamanders survival. State a hypothesis that may be used in such a study.

I think that the worse the quality of the water is the more negative effects it is going to have on the salamanders and the better the quality of the water is the more positive effects it is going to have on the salamanders because the in other study’s the more polluted a body of water was the more defects animals had that used that body of water

Yes they are correct good day
