g) In which region is the average price of a pack of cigarettes the highest ? In which region is per capita cigarette consumption the highest ? 3. Simple linear regression Estimate a first order simple linear regression model where "consumption " is the outcome of interest and "cig_price " is the predictor 61) f) g) Write the estimated regression equation Interpret the coefcient on the "cig_price " variable . Is the estimated coefcient on the "cig_price " variable statistically signicant ? How do you know ? Interpret the model's Rsquared . u n Provide a scattetplot between "consumption and cig_price " that includes the estimated regression equation Use your estimated model to predict per capita cigarette consumption in a state where the average price of a pack of cigarettes is $4. Explain whether it is meaningful to interpret the estimated intercept in your model . 4. Multiple linear regression a) New include "med_income" as a predictor in the model that you estimated for question 3. Interpret the estimated coefficients
