SOLUTION: If the equation of the regression line between two variables x and y is given by the equation (y-hat) = 2 - 3.1x for values of x between 1 and 10, and the correlation coefficient r

Question 1031587: If the equation of the regression line between two variables x and y is given by the equation (y-hat) = 2 - 3.1x for values of x between 1 and 10, and the correlation coefficient r = -0.92 consider the following statements and identify which are true.

I) 92% of the variation in y is explained by the x variable
II) Indications are there is a strong negative correlation between y and x
III) Indications are there is a strong positive correlation between y and x
IV) If x = 5, one would estimate y = -13.5

A Only I and IV are true
B Only I, II, and IV are true
C Only I, III and IV are true
D Only II and IV are true
E Only III and IV are true
