Question

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 the size of the 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 (d) Find the predicted size of the hunting region for an extended pack of 78 wolves. (Use 2 decimal places.) km²/1000 (f) Use a 1% level of significance to test the claim that β > 0. (Use 2 decimal places.) t critical t
