Explanation / Answer

Scatterplot 1 shows a negative relationship between x and y,

since as x increases, y decreases. The relationship is linear

and except for a few points the line is almost straight. So, a

possible value of r would be - 0.741. (Ans).

Scatterplot 2 is almost random and there is no strong

relationship. Hence, a possible value of r would be - 0.382.

(Ans).

Scatterplot 3 is almost a straight line and the relationship

between x and y is negative. So, a possible value if r is - 0.998.

(Ans).

Scatterplot 4 is almost straight line and the relationship

between x and y is positive. So, a possible value of r would be

0.998. (Ans).

Scatterplot 5 is a perfect straight line and the relationship

between x and y is negative. Hence, a possible value of r

would be -1. (Ans).
