Which associations best describe the data in the table?
variable x- 1 2 5 6 3 4 6 7 5
variable y-120 115 89 40 100 80 70 50 60

b. negative association
c. nonlinear association
d. positive association
( .. it's urgent. < 3)

The higher value of X is associated with a lower value of Y so this is a negative association. It is also a nonlinear association because the ratio of change is not constant. For example X changes from 1 to 2, Y changes from 120 to 115 opposed to X changes from 5 to 6 while Y changes from 89 to 40.
