Problem 37

Acid rain Biologists studying the effects of acid rain on wildlife collected data from 163 streams in the Adirondack Mountains. They recorded the pH (acidity) of the water and the BCI, a measure of biological diversity. Heres a scatterplot of BCI against pH: And here is part of the regression analysis: Dependent variable is: BCI R-squared = 27.1% s = 140.4 with 163 - 2 = 161 degrees of freedom Variable Coefficient SE(Coeff) Intercept 2733.37 187.9 pH -197.694 25.57 a) State the null and alternative hypotheses under investigation. b) Assuming that the assumptions for regression inference are reasonable, find the t- and P-values. c) State your conclusion.
