As the oxygen level in water decreases, the population of fish decreases.

Answer 1

The statement that correctly suggests a positive correlation is:

As the oxygen level in water decreases, the population of fish decreases.

This implies that as one variable (oxygen level) decreases, the other variable (population of fish) also decreases, indicating a negative correlation. However, if you were looking for a statement indicating that as one increases, the other also increases (a proper positive correlation), none of the provided statements fit that criteria exactly.

If rewritten to show a positive correlation, an example could be: "As the oxygen level in water increases, the population of fish increases."

So, in the context of your query, none of the responses indicate a positive correlation.
