Please help me with Business Statistics and Quantitative Analysis homework.

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 the past 6 weeks by selecting the appropriate dates and clicking on Download to Spreadsheet at the bottom of page.
2. 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.
3. Calculate the mean and standard deviation of the daily stock changes by running the Descriptive Statistics in Excel Data Analysis. Share the summary table.
4. Consider the mean, median and mode (if it exists). Is your daily stock change distribution right skewed (median < mean), left skewed (mean < median), or symmetric (mean median)? What other considerations would you look at to determine whether or not this distribution is approximately normally distributed?
