In a study of pollution in a water stream, the concentration of pollution is mea-sured at 5 different locations. The locations are at different distances to thepollution source. In the table below, these distances and the average pollutionare given:Distance to the pollution source (in km)246 8 10Average concentration11.5 10.2 10.3 9.68 9.32a) What are the parameter estimates for the three unknown parameters inthe usual linear regression model: 1) The intercept (Bo), 2) the slope (B1)and 3) error standard deviation (o)?

Wolf packs tend to be large extended family groups that have a well-defined hunting territory. Wolves not in the pack are driven out of the territory or killed. In ecologically similar regions, is the size of an extended wolf pack related to size of hunting region? Using radio collars on wolves, the size of the hunting region can be estimated for a given pack of wolves. Let x represent the number of wolves in an extended pack and y represent the size of the hunting region in km2/1000. The following data are representative of one of the national parks. x wolves 29 37 22 61 94 y km2/1000 7.35 12.18 8.15 15.39 16.81 (a) Verify that Σx = 243, Σy = 59.88, Σx2 = 15,251, Σy2 = 788.2256, Σxy = 3362.04, and r ≈ 0.9135.
