A model predicts \(66\), but the observed value is \(72\). What is the residual, defined as observed minus predicted?

Let's work it out together.

Work through one checkpoint at a time. Your answer area opens after the reasoning.

Checkpoint 1

Residual equals observed minus predicted.
Checkpoint 2

Keep the subtraction order fixed.
Checkpoint 3

A positive residual is above the model; a negative residual is below it.
