column 3 is the size in hundreds of square feet. (a) Plot price vs size. Do you see a linear relationship? (b) Obtain the equation of the line regression fits to the data. Plot the regression fitted line on the scatterplot. What price do you predict for a house with size 20 ? (c) Do you notice anything unusual in the scatterplot ? (d) Obtain the correlation between the size and price. Square it. Compare this value to the "R-sq" value on the regression output.
