Please help me with this one.

1) Choose your favorite company or brand and search finance.yahoo.com with that company name and "historical stock prices". Download the stock history for this company for thepast 6 weeksby selecting the appropriate dates and clicking on "Download to Spreadsheet" at the bottom of page.

2) Can you calculate the daily change in the closing stock prices by taking the difference between the closing and opening price for the day? This is the daily stock change? By running the Descriptive Statistics->Summary Table in Excel Data Analysis on the daily stock change, can you share the summary table? Can you calculate the 1st and 3rd quartiles of the daily stock change and share these along with the min, median, and max from 3) as your 5-Number Summary? Can you have a Box & Whiskers Plot using your 5-Number Summary?
