What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
It is given that:
The value of the correlation coefficient r = -0.97
As we know,
If the value of the correlation coefficient is positive it represents the line of best-fit increasing.
If the value of the correlation coefficient is negative it represents the line of best fit decreasing.
If the value of r is close to 1 then we can say that the correlation between the two variables is very strong.
Thus, the points all lie very close to the line of fit, and the line is decreasing option (A) is correct.
