Write the equation of the regression line. Do you think the line gives accurate predictions? Why? (b) Delete the observation with largest x value from the data set. Redo the Data Analysis to obtain the new equation of the regression line and the new Line Fit Plot calculations for the new data set. Write the equation of the regression line. Does this observation greatly affect the equation of the line? Compare the signs of the slopes of the two regression lines
