Can a cat's body weight predict its heart weight? Data was gathered from a random sample of 250 domestic cats. For each cat, the body weight (in kilograms) and the heart weight (in grams) were recorded. It was observed that r-squared was equal to 64.7%, and the regression equation was: Predicted heart weight = -0.36 + 4.03 (body weight). From this information, what should we conclude? O The correlation between body weight and heart weight would not change if we measured body weight in grams rather than kilograms. O The correlation between body weight and heart weight is negative. O The correlation between body weight and heart weight is weak. The units for r would be "grams per kilogram." O For each one kilogram increase in body weight, we predict heart weight to decrease by 0.36 grams
