The statement "there is a strong relationship showing that as the number of days increases, the height of the plants increases" 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]
Here, the value of the correlation coefficient is 0.85
As we know, when the value of r is near to 1, the correlation is strong.
And when r > 1, the relation between x and y such that as x increases, y also increases.
Thus, the statement "there is a strong relationship showing that as the number of days increases, the height of the plants increases" is correct.
