U.S. versus overseas stock returns. How are returns on common stocks in overseas markets related to returns in U.S. markets? Consider measuring U.S. returns by the annual rate of return on the Standard & Poor’s 500 stock index and overseas returns by the annual rate of return on the Morgan Stanley Europe, Australasia, Far East (EAFE) index. Both are recorded in percents. Here is part of the Minitab output for regressing the EAFE returns on the S&P 500 returns for the 25 years 1989 to 2013.

10.62 Estimating the standard error of the slope.
The standard deviation of the S&P 500 returns for these years is 18.70%. From this and your work in the previous exercise, find the standard error for the least-squares slope . Give a 90% confidence interval for the slope of the population regression line.
