Determine the regression equation for the data. Round the final values to three significant digits, if necessary. 0 3 4 12 y 8 6. 12 O A. ý = 4.88 + 0.525x O B. y = 4.98+ 0.725x OC. y = 4.98 + 0.425x O D. y = 4.88 + 0.625x 2.

Use the regression equation to predict the y-value corresponding to the given x-value. Round your answer to the nearest tenth. Nine pairs of data yield the regression equation y = 19.4 +0.93x. Predict y for x= 49. O A. 64.7 O B. 79.6 O C. 57.8 O D. 65.0

Find the regression equation, letting the diameter be the predictor (x) variable. Find the best predicted circumference of a marble with a diameter of 1.9 cm. How does the result compare to the actual circumference of 6.0 cm? Use a significance level of 0.05.
