Lois said, "Point A has a very large negative residual and an x-value near the mean of the rest of
the points, so it's an outlier, but not a high-leverage point. Removing it would lower the entire
regression line, so the y-intercept would decrease."
What is the first mistake in Lois's response?
Choose 1 answer:
B
Point A is not an outlier.
Point A is a high-leverage point.
Removing this point would raise the regression line, not lower it.
Removing this point would increase the y-intercept, not decrease it.
