To the right is a regression analysis of tar and nicotine content of cigarettes. Use the information to answer pans a through e below. Dependent variable is: Nicotine R-Squared = 87.4% s = 0.105 Variable Intercept Tar Coefcient 0.045 0,191 a) Write the equation of the regression line. Nicotine= + Tar b) Estimate the nicotine content of cigarettes with 1.63 milligrams of tar. The cigarettes are expected to have a nicotine content of mg. (Round to three decimal places as needed.) c) Interpret the meaning of the slope of the regression line = b0 + b1x in this context. 0 A.
