Question

what does a residual value of -4.5 mean in reference to the line of best fit? the data point is 4.5 units above the line of best fit. the data point is 4.5 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 -4.5.

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 data point is below the line of best - fit. Here, a residual of - 4.5 means the data point is 4.5 units below the line of best - fit.

Answer:

The data point is 4.5 units below the line of best fit.
