• The height of a student does not depend on their birth month.

• As the month progress, the heights of the students decrease.

• As the months progress, the heights of the students are the same.

The scatter plot shows the relationship between the birth month of every student in Mari's class and their height. Which best describes the association of the scatter plot?

The scatter plot shows the weight of different cars and their cost. Determine whether or not the line of fit is an accurate representation of the relationship of the data.

• Since most of the points lie close to the line, the model is a good fit.

• Since most of the points lie close to the line, the model is not a good fit.

• Since most of the points do not lie close to the line, the model is not a good fit.

• Since most of the points do not lie close to the line, the model is a good fit.
