1. Which of the following statements concerning correlation and regression is true: If the correlation between x and y is negative, then the slope of the regression line that predicts y from x will be negative. O If the correlation between x and y equals 0.7, then 70 percent of the variability in the y-variable is explained by the regression. If the correlation between x and y is high, then it is always appropriate to use regression to predict y from x. O If the correlation between x and y is negative, then it is never appropriate to use regression to predict y from X.
