Question

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 r² = 0.158. Select two conclusions that the researcher can make from this data. a.) The correlation coefficient, r, is 0.397. b.) About 16% of the variation in value of the car is explained by a linear relationship with the age of the car. c.) The correlation coefficient, r, is 0.025. d.) About 84% of the variation in the value of the car is explained by a linear relationship with the age of the car.

          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 r² = 0.158.
Select two conclusions that the
researcher can make from this data.
a.) The correlation coefficient, r, is 0.397.
b.) About 16% of the variation in value of
the car is explained by a linear
relationship with the age of the car.
c.) The correlation coefficient, r, is
0.025.
d.) About 84% of the variation in the
value of the car is explained by a
linear relationship with the age of the
car.
