Use the value ofthe linear correlation coei'cient to calculate the coefcient of determination. What does this tell you about the explained variation of the data about the regression line? About the unexplained variation? r= o.am Calculate the inefcient of determination. (Round to three decimal places as needed.) What does this tell you about the explained variation ofthe data about the regression line? % oi the variation can be explained bythe regression line. (Round to one decimal place as needed} About the unexplained van'ation? % of the variation is unexplained and is due to other factors or to sampling error. (Round to one decimal place as needed.)
