The article “Effect of Temperature on the pH of Skim Milk” (Journal of Dairy Research : 277– 280) reported on a study involving x = temperature (8C) under specified experimental conditions and y = milk pH. The accompanying data (read from a graph) are a representative subset of that which appeared in the article:
Do these data strongly suggest that there is a negative linear relationship between temperature and pH? State and test the relevant hypotheses using a significance level of .01.
