Using the data in the Excel file under the tab Problem1, develop a regression equation for a country’s lung cancer death rate based on cigarette consumption. Is this a good regression model? Why or why not? If Cigarette Consumption was 725, what would you predict the Lung Cancer Death Rate to be? Using your regression model, what is the Residual Value for Finland? Do you think there are any outliers in the model? If so, what would you do with them? Country...
