A researcher found a study relating the mortality rates for women aged 65 to 74, y, to the proportion of calories from sweeteners in their diets, 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.)

The correlation coefficient, r, is 0.514.

B.)

The correlation coefficient, r, is 0.236.

C.)

About 70% of the variation in proportion of calories in sweeteners is explained by a linear relationship with mortality rates.

D.)

About 49% of the variation in mortality rates is explained by a linear relationship with the proportion of calories in sweeteners.

E.)

The correlation coefficient, r, is 0.697.

F.)

About 51% of the variation in mortality rates is explained by a linear relationship with proportion of calories in sweeteners.
