The linear correlation coefficient between the weight of a car and its miles per gallon in the city is r= - 0.978. The least-squares regression line treating weight as the explanatory variable and miles per gallon as the response variable is y = - 0.0060x + 41.4173. Complete parts (a) and (b) below. Click the icon to view the data table. (a) What proportion of the variability in miles per gallon is explained by the relation between weight of the car and miles per gallon? The proportion of the variability in miles per gallon explained by the relation between weight of the car and miles per gallon is% (Round to one decimal place as needed.)

For these data, the least-squares regression line is y= - 0.006x + 41.449. A twelfth car weighs 3,425 pounds and gets 13 miles per gallon. (a) Compute the coefficient of determination of the expanded data set. What effect does the addition of the twelfth car to the data set have on R2? (b) Is the point corresponding to the twelfth car influential? Is it an outlier? Click the icon to view the data table. (a) The coefficient of determination of the expanded data set is R2 =% (Round to one decimal place as needed.)
