Question 929468: Suppose that data was collected for values of x between -10 and + 10 and the corresponding values of y were recorded to compute the equation of the least squares regression line given by the equation below along with the value of the coefficient of determination. Which of the following statements are true?

y = -2.35x+15.47
r^2 = .81

I) When x = 4, the predicted value of y is 6.07
II) For every one unit increase in x, the predicted value of y will increase by 15.47 units
III) The value of the correlation coefficient r is .9

A I only

B II only

C III only

D I and III only

E I, II and III are all true statements
