The Center for Disease Control (CDC) is interested in knowing if there are state-level population characteristics that predict the occurrence of breast cancer death rates and the occurrence of lung cancer death rates. The data file Staten, whose variables are described in the chapter appendix, contains a number of variables that could be possible predictors when used in combination. Your task is to develop multiple regression models that will determine which of the K variables in the data file predict the breast cancer death rate and which predict the lung cancer death rate. Interpret your final regression model, including a discussion of the coefficients, their Student's t's, the standard error of the estimate, and R2.
