(Round your answer to four decimal places.) r = (b) Calculate the value of the correlation coefficient between sale price (in millions of dollars) and land-to-building ratio. (Round your answer to four decimal places.) (c) If you wanted to predict sale price and you could use either size or land-to-building ratio as the basis for making predictions, which would you use? O size O land-to-building ratio (d) Based on your choice in part (c), find the equation of the least-squares line you would use for predicting y = sale price (in millions of dollars). (Leave the data in the original units. Round your answers to four decimal places.)
