Form 20 equally-weighted portfolios each of one, two, five, 10, 15, 20, and 25 stocks by randomly selecting the stocks for each portfolio from among the 105 in the file Stock Returns 2006-2019. You will end up with 140 portfolios (7 size groups x 20 portfolios in each). Compute the population standard deviation of return of each portfolio for the most recent 66 months covered by the data, and then record the average standard deviation for each size group in the template file Results Table. Use at least six-decimal point precision for your calculations and format your entries as real numbers (0.038527 not 3.8527%). Also present your results in a drop-dead gorgeous graph of average portfolio standard deviation against number of stocks in a portfolio, including a caption that anyone can understand.
