Exercise 1: Data Interpretation Table 1: Water Quality vs. Fish Population Dissolved Oxygen | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | Number of Fish Observed | 0 | 1 | 3 | 10 | 12 | 13 | 15 | 10 | 12 | 13 | 1. What patterns do you observe based on the information in Table 1? -The more dissolved oxygen in the water, the more fish is observed in that area of water. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. -If there is more dissolved oxygen in the water, there will be more fish present in the area the water sample is taking from. 3. What would your experimental approach be to test this hypothesis? -I…show more content…
3. Four friends decided to go out and play horseshoes. They took a picture of their results shown to the right: 4. A local grocery store was holding a contest to see who could most closely guess the number of pennies that they had inside a large jar.
