Textbook Question
Chapter 2, Problem 77E
Acid rain Two researchers measured the pH (a scale on which a value of 7 is neutral and values below 7 are acidic) of water collected from rain and snow over a 6-month period in Allegheny County, Pennsylvania:
4.57 5.62 4.12 5.29 4.64 4.31 4.30 4.39 4.45
5.67 4.39 4.52 4.26 4.26 4.40 5.78 4.73 4.56 5.08
4.41 4.12 5.51 4.82 4.63 4.29 4.60
- a) Describe their data with a graph and a few sentences.
- b) Open the data file to find the dates. Consider the dates corresponding to the least acidic (highest pH) days. Do they have anything in common? (You may need to consult a calendar.)
