A researcher found a study relating the distance a driver can see, y, to the age of the driver, x. When researchers looked at the association of x and y, they found that the coefficient of determination was. Select a conclusion that the researcher can make from this data.

• a.)About 74% of the variation in the driver's age is explained by a linear relationship with the distance that the driver can see.
• b.)The correlation coefficient, r, is -0.736.
• c.)The correlation coefficient, r, is -0.271.
• d.)About 46% of the variation in distance that the driver can see is explained by a linear relationship with the driver's age.
