Question 1

Bridget drew the trend line shown in the following scatter plot. Which statement best explains whether the trend line is a good fit for the data?

The trend line is a good fit for the data because it passes through two of the data points.

The trend line is not a good fit for the data because most of the data points are below the trend line.

The trend line is not a good fit for the data because there is an outlier.

The trend line is a good fit for the data because the data represent a positive association, and the line has a positive slope.

Question 2
