The paired data use vehicle age as the explanatory variable and resale value as the response variable
Let \(x\) represent vehicle age and \(y\) represent resale value. The fitted model is:
For each case, calculate the predicted response, then residual = actual response minus predicted response
The paired data and selected fitted values are shown below
Complete the selected predicted-response and signed-departure entries
Which plot matches the signed departures from the fitted line?
