A researcher studies house cats and wants to determine if there is a correlation between the weight of a cat (lbs) and the running speed of a cat (mph). After studying 100 cats the researcher determines the linear regression equation y x = − 54 2.2 . a. Do you think that the weight of a cat is the explanatory or response variable? b. Predict the running speed of cat that weighs 12 pounds. c. Predict the running speed of a cat that weighs 20 pounds. d. The correlation coefficient is found to be r = −0.956 , why do you think it’s negative? e. Do you think the linear regression line makes good predictions? Why or why not
