zion 11 of 15 > Suppose a researcher collects data on the gas mileage, measured in miles per gallon, for both city and highway driving for 35 cars. The data is plotted with city gas mileage on the horizontal axis and highway gas mileage on the vertical axis. The 1965 Triumph Herald is an outlier in the x-direction. What must be true about this car? O This car is an influential observation. M The highway gas mileage for this car is much higher or much lower than the rest of the cars in the data set. O The absolute value of the residual of this car is large. O The city gas mileage for this car is much higher or lower than rest of the cars in the data set. O The highway gas mileage for this car is much higher or lower than other cars in the data set that have similar city gas mileage. about us careers privacy policy terms of use contact us help US 9 O 4:23

Two lines are proposed to describe the relationship between x and y for a particular data set. Shown below are the lines and the sum of squared error for each line. Line1: yˆ  = 5+ 4x, Sumofsquarederror= 48.6 Line2: yˆ = 6 + 3.5x, Sumofsquarederror= 40.8  One of these two lines is the regression line. Which line is the regression line?
