Describing Association

The scatterplot shows the relationship between height (in cm) and arm span (in cm).

The line of best fit equation is y = 0.95x + 9.4.

Predict the heght if the arm span is 183 cm.

• Strong, Negative

• Weak, Positive

• Weak, Negative

The scatterplot shows the relationship between test scores and number of hours studying for a very difficult exam.

The line of best fit equation is: y = 10x + 30.

Predict your test score if you studied for 4.5 hours.

• 75

• 45

• 60

• 80
