Question 2: Problem 2.37 from the text. Use excel to construct a scatter plot. Compute the correlation coefficient “by hand”. You may use excel to do the hand computations. In other words you may use excel to sum up the column compute the squares of each column, etc. You may hand write this and upload an image of your handwritten work. Answer any question in a word document. Mutual fund performance. Many mutual fund compare their performance with that of a benchmark an index of the returns on all securities of the kind that the fund buys. The Vanguard International Growth Fund for example, takes as it benchmark the Morgan Stanley stock market performance. Here are the percent returns for the fund and for the EAFE from 1982 (the first full year of the fund’s existence) to 2000
