What does this tell you about the explained variation of the data about the regression line? About the unexplained vanation? r0.067 Calculate the coeficient of determination (Round to three decimal places as needed) What does this tell you about the explained variation or the data about the regression ine? { 7% of the variation can be explained by the regression line Round to one decimal place as needed.) About the unexplained vanation? % of the variation s unexplained and is due to other factors or to sampling error Round to one decimal place as needed ) answer boxes

Explanation / Answer

Ans:

Given that

r=-0.067

a)cofficient of determination=R2=(-0.067)^2=0.004

b)Explained variation is indicated by R2,so 0.004*100=0.4%

c)Unexplained variation=(1-R^2)*100=(1-0.004)*100=0.996*100=99.6%
