Question

which residual plot shows that the model is a good fit for the data?

Explanation:

A good - fit model's residual plot has randomly scattered points around the horizontal axis. In the first plot, the points show a pattern (a curve - like shape), indicating a poor fit. In the second plot, the points seem somewhat clustered and not truly random. In the third plot, the points are randomly scattered around the horizontal axis, which is a sign that the model is a good fit for the data.

Answer:

The third residual plot.
