If x is the return on U. S. stocks (%) and y is the return on overseas stocks (%) in the same year, the least-squares regression line for predicting y from x is y = -2.7 + 0.47x. You think U. S. stocks will have a return of 10% in 1999. Using this regression line, you predict that the return on overseas stocks will be (a) 7.4% (b) -2.23% (c) 2% (d) 3.17% (e) 27%
