Question

select the correct answer.
the scatter - plot shows the number of albums sold from 2006 to 2011. what is the association between the two quantities?
a. positive linear association
b. negative linear association
c. positive nonlinear association
d. negative nonlinear association

Explanation:

Step1: Observe the scatter - plot trend

As the years (x - values) increase from 2006 to 2011, the number of albums sold (y - values) decreases.

Step2: Determine the type of association

A negative association means that as one variable increases, the other decreases. Since the points seem to follow a somewhat linear pattern (they roughly form a line - like shape), it is a negative linear association.

Answer:

B. negative linear association
