The dataset "Condos2" contains the selling price and living area for a random sample of condos in Vancouver. The dataset is downloaded from http://mylinux.langara.bc.ca/~sli/regression/condos2.csv

g. [1] Is it appropriate to predict the selling price of a condo with the size of 3000 2 using the regression equation? Explain.

h. [1] Is it appropriate to estimate the selling price of a house with the size of 1000 2 using the regression equation? Explain.

i. [1] Explain what linearity condition means in the context of the problem.

j. [1] Explain what constant variance condition means in the context of the problem.

k. Obtain the residual plot to check the linearity and constant variance conditions for the regression analysis.

I. [1] Is the linearity condition valid?

II. [1] Is the constant variance condition valid?
