- (a) State the null and alternative hypotheses.
- (b) Verify that the requirements to use the one-way ANOVA procedure are satisfied. Normal probability plots indicate that the sample data come from a normal population.
- (c) Test the hypothesis that the mean pHs in the rainwater are the same at the α = 0.05 level of significance.
- (d) Draw boxplots of the pH in rain for the three states to support the results obtained in part (c).
