Is the regression model statistically significant (Yes or No)? 2. Highlight the cell in green that corresponds to the statistic value you used to answer question #1. 3. For each unit increase in SqFt, how much does Sell Price change? 4. A variable should be added to the model if it causes the Adjusted R Square to decrease (True or False)? 5. For each unit increase in Age, how much does Sell Price change? 6. How much does Sell Price change if the condition is Excellent? 6. How much variability (in %) in Sell Price, can be explained by the regression model with SqFt, Age, and Condition as the independent variables? 7.
