For this assignment, you will practice applying statistical inference to business decision scenarios.

Practical Application Scenario 1

Using the Yahoo Finance Web site as in Module 1, download a separate five years of daily data for a stock that begins with the first letter of your first name this time.(JP Morgan) Be sure that you match the exact dates that you used for the initial stock data, so that you can combine the spreadsheets by pasting.

Now, you are interested in seeing if the mean daily closing volume of the two stocks are statistically different when accounting for daily volatility of the market. In other words, you want to conduct a paired t-test using Date as the variable for pairing. To complete this analysis, do the following:

1. State the null and alternative hypotheses via both an explanation and a math equation.
2. Identify the appropriate statistical test. State this clearly.
3. Conduct the test and state whether to accept or reject the null hypothesis using the p-value and an alpha of .05. You may solve the equation manually, use the Analysis ToolPak add-in for Microsoft Excel, or use the SAS Enterprise Guide.
4. Report the rejection or acceptance of the null in terms of the scenario results using laymen’s terms. For this scenario, write a three-sentence paragraph that details why you can be statistically confident that the mean  adjusted closing price has increased, decreased, or remained the same, and what would happen if alpha was .01.

You will need to use Excel or SAS to complete this test.

Practical Application Scenario 2

Now, use only the original stock data, those data associated with the first letter of your last name. You are interested in whether the mean daily adjusted closing price for the last three years has increased from the mean daily adjusted closing price of the first two years. Conduct a two-sample hypothesis test by doing the following.

1. State the null and alternative hypotheses via both an explanation and a math equation.
2. Identify the appropriate statistical test. State this clearly.
3. Conduct the test and state whether to accept or reject the null hypothesis using the p-value and an alpha of .05. You may solve the equation manually, use the Analysis ToolPak add-in for Microsoft Excel, or use the SAS Enterprise Guide.
4. Report the rejection or acceptance of the null in terms of the scenario results using laymen’s terms. For this scenario, write a three-sentence paragraph that details why you can be statistically confident that the mean adjusted closing price has increased, decreased, or remained the same, and what would happen if alpha was .01.

You will need to use Excel or SAS to complete this test.

Practical Application Scenario 3

You are interested in knowing whether there are differences in the mean daily adjusted closing price for a specific stock. For this practical application, use the 5 years of daily data that you downloaded previously for the stock beginning with the first letter of your last name. Manipulate the data so that you have all of the daily stock data for the days in each month of the year together (for all 5 years), then conduct an ANOVA F-test to see whether there are monthly differences in the mean adjusted closing prices.

1. State the null and alternative hypotheses via both an explanation and a math equation.
2. Identify the appropriate statistical test. State this clearly.
3. Conduct the test and state whether to accept or reject the null hypothesis using the p-value and an alpha of .05. You may solve the equation manually, use the Analysis ToolPak add-in for Microsoft Excel, or use the SAS Enterprise Guide.
4. Report the rejection or acceptance of the null in terms of the scenario results using laymen’s terms. For this scenario, write a three-sentence paragraph that details why you can be statistically confident that the mean adjusted closing price income has increased, decreased, or remained the same, and what would happen if alpha was .01.

For this assignment, you will need to read the Case Study (also listed below) and review the Constructing the Genogram power point for the Genogram Key Symbols. After reading the case study, you will follow the instructions in A Picture Is Worth a Thousand Words: Exploring the Use of Genograms in Social Work Practice to draw a genogram using Microsoft Word. Please be sure to map out all family relationships you are able to identify from the given information, including names, ages and quality of relationship/relationship patterns. After completing the genogram, you will also be expected to include a 2-3 page narrative to address the questions listed below. Be sure to use proper APA format (12 point Times New Roman, double-spaced, one-inch margins) and must include references to your textbook where necessary:

· Explain the connecting lines you identified in relationships between family members (i.e. conflictual, close, enmeshed)

· Who had/has the power in the family?

· What patterns or themes do you see in the family?  How is the communication among members?  

· What are the values this family upholds? 

· How do the family members cope with stress (i.e., become anxious, get angry, drink, are calm and handle it well, etc.)?   

· How will this information be important to you as your work with clients?  What challenges do you think you will have?  

· After examining behavior patterns and family relationships, what other information would you want to gather from this family?

· How would you apply Cognitive Behavioral Therapy when working with this family?

 Case Study 

Marshall, a 32 year old Caucasian male, and Cynthia, a 30 year old Hispanic woman, have been together for over 13 years and married for 9 years. Marshall and Cynthia have three children together: Sylvia, age 11, Jonathan, age 7 and Torrence, age 5. The two met as children as they lived in the same neighborhood. Marshall is an only child and his parents, Judith (age 61) and Randy (age 66) are still married, living in his childhood home. Marshall has a half-brother, Stephen (age 35), the only child from Randy’s previous marriage (name and age of previous partner unknown). Stephen spent weekends with the family until he moved in full time to have a shorter commute to the local community college. After graduation, Stephen moved out of state to begin his career. Judith and Randy allowed Marshall much freedom as a child and often took weekend trips away from home during Marshall’s teenage years, leaving Stephen in charge. Marshall also often spent time at his maternal grandparents’ (Vivian and George, both deceased) home during the summer to visit with his extended family.

Cynthia comes from a very strict Puerto Rican home and is the middle child, having an older sister, Marissa (age 35) and a younger sister, Sophia (age 29). Marissa’s father, William (age 58) is a pastor in the family’s local church and her mother, Patricia (age 56) works with the women’s ministry in the parish. They have been married for 36 years and had moved to the United States shortly after they were married so that William could find better work opportunities. William previously worked as an HVAC laborer and retired at a young age after sustaining an injury on the job. 

Cynthia grew up in a household with very traditional gender roles and the expectation that she would be married before living with a partner, given the family’s Christian beliefs and values. Cynthia’s paternal grandmother, Carmen (age 80) still lives with her parents and Patricia has been her primary caretaker for the past several years. Carmen moved in with the family after her husband Julian passed away. Cynthia threw her family for a loop when she announced her pregnancy with Sylvia, considering that she and Marshall were not yet married. There was quite a bit of pressure for Cynthia and Marshall to marry, however, they chose to buy a home before saving for a wedding. As a result, William and Marshall have a very strained relationship because he blames Marshall for challenging Cynthia’s faith and getting his daughter pregnant and not marrying her right away.

Now that Sylvia is approaching her teenage years, Cynthia and Marshall have been disagreeing about their parenting choices. Marshall believes that Sylvia should be allowed to have a cell phone and a later curfew since she is at an age where social connections are most important. Marshall believes that they have instilled moral principles and responsibility in Sylvia and that she can be trusted to make good choices.

Cynthia believes that Sylvia should still be closely monitored and wants to send her away to an all-girls, Christian camp for the entire summer. Cynthia worries that she will make choices that will impact her future. Since Cynthia was only 19 when she had Sylvia, she had dropped out of college to be a stay-at-home mom. Cynthia has worked hard to raise her children in the church and pushes Sylvia to help out with household chores so that she has an understanding of what adult life is like. Cynthia constantly reminds Sylvia that making the choice to engage in behaviors that may result in her becoming a parent at a young age will increase responsibilities on her shoulders. Sylvia has begun to act out since she feels it is unfair that her brothers are not held to the same expectations and do not need to participate in household chores. Sylvia often feels jealous of her brothers and has begun to argue with her mom about her responsibilities around the house.

Marshall was also in school at the time of Sylvia’s birth and continued his schooling with his parents’ help. Marshall completed his degree and has been working in a very successful accounting firm for 10 years. Cynthia did not return to complete her Associates Degree to become an RN (registered nurse) until she was 25 and has been working in the local hospital for 3 years. With Cynthia’s contribution to the household, the family has been doing quite well financially and is considering moving to a smaller town, about 25 minutes away from where they currently live in their childhood hometown. Marshall and Cynthia have decided that they want to make this move before Sylvia transitions into high school.

After learning of the move, William and Patricia are very upset and have asked that Marshall and Cynthia reconsider and stay close by the rest of the family. Marshall has become very angry and feels like William will never let go of his daughter and that Cynthia makes her decisions based on her father’s approval. As a result, Cynthia and Marshall have been arguing even more. Marshall has also blamed much of their arguing about parenting choices on William since he knows that Cynthia always asks for her father’s input. At this point, Marshall has given Cynthia an ultimatum to choose between their family or her own family. Cynthia is beside herself and cannot understand why Marshall would put her in this position.

For this assignment, you will mainly use IBISWorld to complete a Market Structure Analysis. This assignment was adapted from Core Microeconomics, Chiang, 3rd edition.

IBISWorld:Your journey into a selected industry begins by clicking on the first listing in the gray-shaded box, US Industry Reports (NAICS).

1. Choose TWO specific products. These products MUST be sold in different industries. For example, you could choose domestic airline travel and dish detergent.

Product #1:Product #2:

2. Consider the Market Factors for each product. Please conduct some research on IBISWorld [and outside research] to address TWO to FOUR market factors listed in the Market Factors section below:

a. Market Factor 1 – Number of firms:• Is the industry composed of many firms, each with limited or no ability to set the market price, such as local pizza places, or is it dominated by a large firm such as Wal-Mart that can influence price regardless of the number of other firms?

b. Market Factor 2 – Nature of the product: • Are we talking about a homogeneous product such as salt, for which no consumer will pay a premium or are we considering leather handbags, which consumers may think vary greatly, in that some firms (Coach, Gucci) produce better goods than others?

c. Market Factor 3 – Barriers to entry: • Does the industry require low start-up and maintenance costs such as found at a roadside fruit and vegetable stand, or is it a computer-chip business that may require $1 billion to build a new chip plant?

d. Market Factor 4 – Price control (market power):• For example, pharmaceutical companies can set prices for new medicines, at least for a period of time, because of patent protection. Farmers and copper producers have virtually no control and get their prices from world markets. Possible market structures range from perfect competition, characterized by many firms, to monopoly, where an industry is made up of only one firm.

Factor #1 explanation:Factor #2 explanation:

3. Conduct some additional research, then make a determination regarding the type of market in which the product is sold. In other words, indicate whether it operates in a perfectly competitive, monopoly, oligopoly, or monopolistically competitive market. Justify your response.

Type of Market:

Justification:

For this assignment, you will identify the top three major safety and health issues in a chosen firm, and write a policy on each, consistent with Occupational Safety & Health Administration (OSHA) standards. There is a minimum requirement of 400 words for each of the three job policies.

Each of the five domains of OSHA must be considered when writing these three policies:

a) Hazard communication: How will you notify people of potentially dangerous or unhealthy work conditions? 

b) Blood-borne pathogens: How will you protect employees from blood-borne pathogens such as AIDS?

c) Personal protective equipment (PPE): What equipment or tools will your employees in this job require to work safely? 

d) Cumulative trauma disorders (CTDs): How will you prevent CTDs that come from repetitive movement (e.g., carpel tunnel syndrome)? 

e) Work assignments: How will you handle potentially dangerous work assignments, especially to protect unborn babies?

NOTE: This is a three-part assignment. All three of the policies (400 words each) you write should go on one document. This one document is what will be uploaded to Blackboard.
