Which correlation best describes the strength of the linear association between the number of species added to the United States endangered species list and the year?

• Weak negative correlation, because r ≈ -0.91

• Weak negative correlation, because r ≈ -0.09

• Strong negative correlation, because r ≈ -0.91

• Strong negative correlation, because r ≈ -0.09
