Suppose we estimate the following regression model: House Price = a + b1*square footage + b2*number of bedrooms, and the R-squared value is 0.67. If we add the "number of bathrooms" to the regression, i.e., estimate the following model: House Price = a + b1*square footage + b2*number of bedrooms + b3*number of bathrooms. The R-squared value of the new model cannot be: O 0.68 O All the values listed are possible R-squared values. O 0.92 O 0.66
