Assume that we have a regression model y = bo + 61 2 If we have an observation with a Zx equal to -2.00, and correlation coefficient is r =0.80, how many standard deviations do you expect the predicted value for the response variable (?) to be above or below the mean? (Enter a positive number if it will be above the mean, a negative number if it will be below the mean, and O if it will be right at the mean)
