If the correlation between variables A and B is +0.7, then

A) we can use measurements of A to make moderately accurate predictions of the value of B.
B) the mean value of B is greater than the mean value of A.
C) the mean value of A is greater than the mean value of B.
D) as variable A increases, variable B tends to decrease.

Final Answer : A, Explanation :  A correlation coefficient of +0.7 indicates a moderately strong positive relationship between variables A and B. This means that as variable A increases, variable B tends to increase as well, and vice versa. While it does not necessarily indicate a cause-and-effect relationship between the variables, it does suggest that there is a pattern or trend in their relationship that can be used to make moderately accurate predictions of the value of B based on measurements of A. The mean values of A and B are not necessarily related to the correlation coefficient.
