The model was developed using recently rented units in a particular neighborhood. The rental price (y) is based on the floor area (x) of the unit. The model is. y = 960.39r - 8, 487.26 The coefficient of correlation for the model is 0.92. (a) Use the model to predict the selling price of a house that is 33 square meters. (b) A house with 33 square meters was recently rented out for Php 25,000. Explain why this is not what the model predicted. (c) How much of this model could account to actual rental cost? (d) If you were going to use multiple regression to develop an appraisal model, what other quantitative variables might be included in the model
