This Quiz: 16 pts possible Submit Quiz The table shows the numbers of new-vehicle sales (in thousands) in the United States for Company A and Company B for 10 years. The equation of the regression line is y = 0.981x * 1,244.64. Complete parts (a) and (b) below New-vehicle sales (Company A), x 4,168 3,919 3,565 3,421 3,252 3,099 2,840 2,516 1,936 2.088 New-vehicle sales (Company B), y 4,917 4,873 4,847 4,702 4,643 4,467 4,664 3,807 2,949 2.797 (a) Find the coefficient of determination and interpret the result. (Round to three decimal places as needed.) How can the coefficient of determination be interpreted? The coefficient of determination is the fraction of the variation in new-vehicle sales for that can be explained by the variation in new-vehicle sales for and is represented by The remaining frac of the variation, , is unexplained and is due to other factors or to sampling error. (b) Find the standard error of estimate s, and interpret the result. So = (Round to three decimal places as needed.) How can the standard error of estimate be interpreted? The standard error of estimate of the new-vehicle sales for V for of new-vehicle sales for is about s. Enter your answer in each of the answer boxes. N
