Local environmentalists want to test if there is a difference in the pH of three different streams (called A, B, and C) feeding into Lake Travis. They took a random sample of 15 measurements from each stream and, after confirming all relevant assumptions, ran a one-way ANOVA on the data and got a significant (p<0.05) result.
a. Write the appropriate null and alternative hypotheses for this analysis.
b. List one potential confounding variable.
c. In a post-hoc analysis, they got the following p values. Which pairs of streams have significantly different mean pH? Show work for full credit.
Stream A vs. B: p = 0.003
Stream A vs. C: p= 0.029
Stream A vs. C: p= 0.041
