To find the residual of a data point, you need two pieces of information: the observed value and the predicted value (or the value from a model). The residual is calculated as:
\[ \text{Residual} = \text{Observed Value} - \text{Predicted Value} \]
In this case, you have the observed value of 14.59. However, you need the predicted value corresponding to the data point at four. If you provide the predicted value (from your model or dataset) for the data point at four, I can help you calculate the residual and round it to the nearest thousandth.
