The correlation coefficient of r = 0.45 indicate weak positive correlation option (C) is correct.
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]
We have value of the coefficient of the correlation r = 0.45
As we know the value of r varies between [-1, 1]
r = 1 represents strong positive correlation
r = -1 represents strong negative correlation
As we have r = 0.45 which shows a positive weak correlation.
Thus, the correlation coefficient of r = 0.45 indicate weak positive correlation option (C) is correct.
