In Units 3 and 4 we have moved forward with our discussions as to conflicting loyalty for employees and as to both privacy and diversity in the workplace. However, for this second assignment, the focus is on the laws which protect workers. In conducting your research as to legal concepts or statutes you may draw upon the topics address in Units 2, 3 and 4.

Amazon will be opening new offices in your city. You will be in charge of their Human Resources Department and have been charged with the creation of policies to address the diverse nature of the employees and safety in the workplace. Among the anticipated employees for the company in this new location will be workers who are over 50 years of age, employees with physical disabilities, pregnant women, and those of different racial and ethnicities.

Select and define three legal concepts or statutes which might be used as you develop these new employee policies for Amazon.

Prepare a one-page analysis as to each legal concept or statute.

Use and cite one additional authoritative source for each legal concept or statute other than the text materials.

In addition to fulfilling the specifics of the assignment, a successful memo must also meet the following criteria:

• Length should be 3 pages, excluding your title and references page
• Viewpoint and purpose should be clearly established and sustained.
• Assignment should follow the conventions of Standard English (correct grammar, punctuation, etc.).
• Writing should be well ordered, logical and unified, as well as original and insightful.
• Cite all sources on a separate reference page at the end of your paper and cited within the body of your paper using APA format.
• Your work should display superior content, organization, style, citation, and mechanics in accordance with APA.

Is this Normal?

One theory about the daily changes in the closing price of a stock is that these changes follow a random walk – that is, these daily events are independent of each other and move upward or downward in a random manner – and can be approximated by a normal distribution. To test this theory, collect the most recent closing prices of stocks from for your favorite company or brand. You can find this by going to finance.yahoo.com and searching for “Your Company stock history.” See Example and DB starter video in Unit 4 LiveBinder.

Main Post:

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. Run the Descriptive Statistics->Summary Table in Excel Data Analysis on the daily stock change. Share the summary table.
4. Calculate the 1st and 3rd quartiles of the daily stock change. Share these along with the min, median, and max from 3) as your 5-Number Summary.
5. Create a Box & Whiskers Plot using your 5-Number Summary. (For Help, refer to Unit 2 LiveBinder).
6. Is your daily stock change distribution right skewed (median < mean), left skewed (mean < median), or symmetric (mean ≈ median)? Would you consider your daily stock change to be normally distributed? Why or Why Not?

Peer Reply #1: Read a classmate’s response. Consider investing in your classmate’s stock and assume that the daily change is normally distributed. Using the Normal Distribution Excel template found in Unit 4 LiveBinder, your classmate’s mean and standard deviation, determine the probability for the daily change of this stock to have:

1. A decrease of 0.5 point or more (X ≤ -0.5)?
2. An increase of more than 0.5 point (X > 0.5)?
3. A decrease of 1 point or more (X ≤ -1)?
4. An increase of more than 1 point (X > 1)?

In your own words, explain if these are high or low likelihoods for change. See Example.

Peer Reply #2: Read a different classmate’s response. Consider investing in your classmate’s stock. If you wanted to be 95% sure what the daily change would be, what range for a daily change would you expect? Use the Normal Distribution Excel template found in Unit 4 LiveBinder. See Example.
