The table shows the number of species added to the United States endangered species list each year for several years. A linear function can be used to model the data.

Which correlation best describes the strength of the linear association between the number of species added to the United St​ates endangered species list and the year? ​ (a)   ​

• Weak negative correlations, because r = -.0.09
