Explanation:

Answer 2

Answer: Choice B) negative linear association

=================================

Reasoning:

The points all go downhill as you move from left to right. We can draw a straight line that is fairly close to all of them. This is known as the regression line. The regression line having a negative slope tells us the linear association is negative. This means the correlation coefficient r is negative, so,
`-1 < r < 0` (r = -1 is not possible as not all points fall on the same straight line)
