The regression equation is y=+x. (Round to five decimal places as needed.) The best predicted circumference for a diameter of 1.2 cm is cm. (Round to one decimal place as needed.) How does the result compare to the actual circumference of 3.8 cm? O A. Since 1.2 cm is beyond the scope of the sample diameters, the predicted value yields a very different circumference. O B. Even though 1.2 cm is within the scope of the sample diameters, the predicted value yields a very different circumference. O C.…
