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 here, or use another drawing program.
8. Interpret the data from the graph made in Question 7. (Be sure to use sufficient detail in your interpretation).
9. For each of the following, convert each value into the designated units.
a. 46,756,790 mg = _______ kg
b. 5.6 hours = ________ seconds
c. 13.5 cm = ________ inches
d. 47 °C = _______ °F
