##### Reference no: EM1392387

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?

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.

3. What would your experimental approach be to test this hypothesis?

4. What are the independent and dependent variables?

5. What would be your control?

6. What type of graph would be appropriate for this data set? Why?

7. Graph the data from Table 1: Water Quality vs. Fish Population (found at the beginning of this exercise). You may use Excel, then "Insert" the graph, or use another drawing program. You may also draw it neatly by hand and scan your drawing. If you choose this option, you must insert the scanned jpg image here.

8. Interpret the data from the graph made in Question 7.?
