Ответ:
A data point is 1.3 units above the line of best fit.
The formula for residual value is this:
residual value = observed value - predicted value
The predicted values all lie in the best fit line. So if the residual value is positive, this means that the observed value is greater than the predicted value or the point is above the best fit line.
