Step 1: Find the co-efficient
of correlation r (given in the question). r = (-0.6).
Step 2: Square the co-efficient of correlation
(-0.6)2 = 0.36
The co-efficient of determination is = 0.36

A correlation coefficient is computed to be -0.95 means that the relationship between two variables is weak because it is negative. True/False
QUESTION 6 Suppose the correlation coefficient between two variables is found to be -0.94. Which of the following statements are true? there is a strong tendency for small values of one variable to be associated with large values of the other variable there is a weak negative relationship between the variables a scatter plot of the data points would show a clear downward trend there is a strong tendency for low values of one variable to be paired with low...
