Is the paragraph quoted below from §15.2 ("the broom package") misplaced? Up to this point I don't think there's been any mention of determining if slopes changed. And there doesn't seem to be a plot showing overlapping confidence intervals.
Now we return to discussing our original task of determining if slopes changed. The plot we just made, using summarize and tidy, shows that the confidence intervals overlap, which provides a nice visual confirmation that our assumption that the slope does not change is safe.
