Problem 61 of 7
Interpret residual plot description points are randomly scattered above and below zero with no clear pattern.
Using a hint is okay. It just tells the trainer to give you a little more review.

judge linear model fit as reasonable.
Hidden until you reveal it.
Residual plot must show random scatter rather than a systematic curve or fan pattern.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Check whether residuals are centered around zero.
2. Look for absence of systematic pattern.
3. Conclude whether the model form is reasonable and note residual size if relevant.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying every random residual plot means perfect predictions.
