Answer:
One possible hypothesis that could be developed from this data is that the number of fish observed in the body of water is positively correlated with the amount of dissolved oxygen in the water sample. This hypothesis suggests that as the amount of dissolved oxygen in the water increases, the number of fish observed in the water also increases.
This hypothesis is based on the observation that the number of fish observed in the body of water increases from 0 to 13 as the amount of dissolved oxygen in the water sample increases from 0 to 10 ppm. However, the number of fish observed decreases slightly at 14 ppm and then increases again at 16 ppm. This could suggest a possible threshold effect, where a certain level of dissolved oxygen is necessary for fish survival and growth, but too much dissolved oxygen could also have negative impacts on fish populations.
Overall, this hypothesis could be further tested and refined through additional data collection and analysis, as well as consideration of other factors that could influence fish populations, such as water temperature, pH, and nutrient levels.
Hope this helps!
