An envirоnmentаlist wаnted tо determine if the meаn acidity оf rain differed among Alaska, Florida, and Texas. He randomly selected six rain dates at each the three locations and obtained the data in the data set labeled Acid Rain in My Groups on StatCrunch. Test the hypothesis that the mean pHs in the rainwater are different at the α = 0.05 level of significance. If a statistical difference is found between the groups, clearly identify which group(s), if any, are different using the appropriate test. State the null and alternative hypotheses for this situation.
