Question 29 5 pts An analyst is trying to purchase a large tract of land. The current owner of the tract has already subdivided the land into separate building lots and has prepared the lots by removing some of the trees. The developer wants to forecast the value of each lot. From previous experience, she knows that the most important factors affecting the price of a lot are size, number of mature trees, and distance to the lake. She runs the following multiple regression model for her analysis: Price = ,80 l 51 LotSize + gTrees l g Distance + 5 See below the Parameter Estimates section of the JMP regression output.
