Find the regression equation, letting the diameter be the predictor (x) variable. Find the best predicted circumference of a marble with a diameter of 1.8 cm. How does the result compare to the actual circumference of 5.7 cm? Use a significance level of 0.05. Baseball Basketball Golf Soccer Tennis Ping-Pong Volleyball O Diameter 7.5 23.7 4.4 22.1 7.0 3.9 21.2 Circumference 23.6 74.5 13.8 69.4 22.0 12.3 66.6 Click the icon to view the critical values of the Pearson correlation coefficient r. The regression equation is y = X. (Round to five decimal places as needed.) The best predicted circumference for a diameter of ucm is cm. (Round to one decimal place as needed.) 1- 8 How does the result compare to the actual circumference of 129cm? 5.7 O A. Even though 28 cm is within the scope of the sample diameters, the predicted value yields a very different circumference. O B. Since 428 cm is beyond the scope of the sample diameters, the predicted value yields a very different circumference. O C. Even though oks cm is beyond the scope of the sample diameters, the predicted value yields the actual circumference. O D. Since 4928 cm is within the scope of the sample diameters, the predicted value yields the actual circumference. 1.8
