Biology and Environmental Science Researchers in Canada recently investigated the impacts on birds from the increased use of wind turbines and loss of nesting habitat.35 A random sample of Canadian bird habitats was obtained, and the estimated number of nests (y, per hectare) was recorded for each. In addition, the number of wind farms (x1), number of turbines (x2), and area of the habitat (x3, in ha) was also recorded.
a. Estimate the regression coefficients in the model
b. Interpret the sign of each estimated regression coefficient.
c. Conduct a model utility test using a = 0.05 and find the value of the coefficient of determination.
d. Which predictor variable do you believe is most important? Why?
e. Check the model assumptions by constructing a normal probability plot of the residuals and the appropriate scatter plots.
