To solve the problem we must know about the correlation coefficients.
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
The correlation coefficient 0.715 denotes, "There is a strong positive relationship between x and y".
Given to us
As we can see that the value of the correlation coefficient is 0.715, therefore, it is close to 1 means the relationship is strong, while the '+' symbol denotes that the relationship is positive.
Hence, the correlation coefficient 0.715 denotes, "There is a strong positive relationship between x and y".
