Consider the following information: A) (1.75 points) Use the Pure Premium Method to calculate proposed relativities for Territory 1, 2, and 3. Keep Territory 1 as the base level. B) (0.25 points) Suppose that while working on the proposed rate change you discover that territory 3 has a higher proportion of homes that are worth >$750,000 than territory 1 and territory 2. What procedure could you use to help improve your analysis from part A)? C) (0.25 points) Assuming that territory 3 has a higher proportion of more expensive homes, how might you adjust the relativities selected in part A)? No calculations needed for this part
