Question

what does a residual value of -0.8 mean in reference to the line of best fit? the given point is 0.8 units above the line of best fit. the given point is 0.8 units below the line of best fit. the line of best fit is not appropriate to the data. the line of best fit has a slope of 0.8.

Explanation:

The residual is the difference between the observed - value and the predicted - value from the line of best fit. A negative residual means the observed value (the given point) is below the predicted value (the line of best fit). Here, a residual of - 0.8 means the given point is 0.8 units below the line of best fit.

Answer:

The given point is 0.8 units below the line of best fit.
