According to your data, was your hypothesis correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. list at least two real world examples that apply the findings of this experiment. (hint: an example of this type was given in the introduction to this project.)
