Problem 92 of 7
Compare models using residual summaries -5, 2, -3, 4, 0 and -1, 0, 1, -0.5, 0.5.
Using a hint is okay. It just tells the trainer to give you a little more review.

choose model with smaller/more random residuals.
Hidden until you reveal it.
Residual evidence must allow comparison of size, randomness, or bias.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Compare residual sizes.
2. Check whether residuals are centered around zero.
3. Prefer the model with smaller and more random residuals.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Choosing by equation simplicity when residual evidence is requested.
