Suppose that a scatter diagram depicts a relationship between the two variables that can be summarized by a straight line.The correlation coefficient is computed and results in a value of -0.73.Which of the following is NOT TRUE?
A)There is a linear relationship between the two variables.
B)In general, an increase in one variable is associated with an increase in the other variable.
C)In general, an increase in one variable is associated with a decrease in the other variable.
D)Even though the correlation coefficient is less than zero, it still communicates the strength of the linear relationship.
