Question

What's the interpretation for the following graph?

(b) Estimate the linear equation using least squares. Interpret the fitted intercept and slope. Be sure to include their units. Note if either estimate represents a large extrapolation and is consequently not reliable. Complete the equation for the . fitted line below Estimated Horsepower (HP) = 38.729 + (68.816) Engine Size (L) (Round to three decimal places as needed.) Interpret the fitted intercept. Note if the estimate represents a large extrapolation and is consequently not reliable. Select the correct choice below and fill in the answer box(es) within your choice. (Round to three decimal places as needed.) O A. The intercept is 38.729 HP. For every one liter of engine size increase, the average horsepower increases by 68.816 HP O B. The intercept of HP represents the average horsepower. O C. The intercept is 38.729 liters. For every horsepower increase, the average engine size increases by 68.816 liters O D. The intercept of HP is a large extrapolation and not directly interpretable.

Explanation / Answer

The interpretation is : The intercept is 38.729 and for every one liter of engine size increase, the average horsepower increases by 68.816. so option A is correct
