A researcher found a study relating the value of a car, y, to the age of the car, x. When researchers looked at the association of x and y, they found that the coefficient of determination was .
Select TWO conclusions that the researcher can make from this data.
- a.)
- About 16% of the variation in value of the car is explained by a linear relationship with the age of the car.
- b.)
- The correlation coefficient, r, is 0.842.
- c.)
- About 84% of the variation in the value of the car is explained by a linear relationship with the age of the car.
- d.)
- About 40% of the variation in the age of the car is explained by a linear relationship with the value of the car.
- e.)
- The correlation coefficient, r, is 0.397.
- f.)
- The correlation coefficient, r, is 0.025.
