Question

An environmentalist wanted to determine if the mean acidity of rain differed among Alaska, Florida, and Texas. He randomly selected 6 rain dates at each of the 3 locations and obtained the following data (pH of rain):

Alaska	Florida	Texas
5.41	4.87	5.46
5.39	5.18	5.89
4.90	4.52	5.57
5.14	5.12	5.15
4.80	4.89	5.45
5.24	5.06	5.30

Conduct a full hypothesis test. Be sure to:

• check conditions

1. state hypotheses
2. find the test statistic and df (both)
3. state significance level
4. find p-value and draw/shade the graph
5. make a decision
6. write a conclusion
