- 1. About Your Signature Assignment.docx About Your Signature Assignment – Due Monday, 20-November This signature assignment is designed to align with specific program student learning outcome(s) in your program. Program Student Learning Outcomes are broad statements that describe what students should know and be able to do upon completion of their degree. The signature assignments might be graded with an automated rubric that allows the University to collect data that can be aggregated across a location or college/school and used for program improvements. Purpose of Assignment The purpose of this assignment is for students to synthesize the concepts learned throughout the course. This assignment will provide students an opportunity to build critical thinking skills, develop businesses and organizations, and solve problems requiring data by compiling all pertinent information into one report. Assignment Steps Resources: Microsoft Excel®, Signature Assignment Databases, Signature Assignment Options, Part 3: Inferential Statistics Scenario: Upon successful completion of the MBA program, say you work in the analytics department for a consulting company. Your assignment is to analyze one of the following databases: · Manufacturing · Hospital · Consumer Food · Financial Select one of the databases based on the information in the Signature Assignment Options. Provide a 1,600-word detailed, statistical report including the following: · Explain the context of the case · Provide a research foundation for the topic
- 2. · Present graphs · Explain outliers · Prepare calculations · Conduct hypotheses tests · Discuss inferences you have made from the results This assignment is broken down into four parts: · Part 1 - Preliminary Analysis · Part 2 - Examination of Descriptive Statistics · Part 3 - Examination of Inferential Statistics · Part 4 - Conclusion/Recommendations Part 1 - Preliminary Analysis (3-4 paragraphs) Generally, as a statistics consultant, you will be given a problem and data. At times, you may have to gather additional data. For this assignment, assume all the data is already gathered for you. State the objective: · What are the questions you are trying to address? Describe the population in the study clearly and in sufficient detail: · What is the sample? Discuss the types of data and variables: · Are the data quantitative or qualitative? · What are levels of measurement for the data? Part 2 - Descriptive Statistics (3-4 paragraphs) Examine the given data. Present the descriptive statistics (mean, median, mode, range, standard deviation, variance, CV, and five-number summary). Identify any outliers in the data. Present any graphs or charts you think are appropriate for the data. Note: Ideally, we want to assess the conditions of normality too. However, for the purpose of this exercise, assume data is drawn from normal populations. Part 3 - Inferential Statistics (2-3 paragraphs) Use the Part 3: Inferential Statistics document. · Create (formulate) hypotheses
- 3. · Run formal hypothesis tests · Make decisions. Your decisions should be stated in non- technical terms. Hint: A final conclusion saying "reject the null hypothesis" by itself without explanation is basically worthless to those who hired you. Similarly, stating the conclusion is false or rejected is not sufficient. Part 4 - Conclusion and Recommendations (1-2 paragraphs) Include the following: · What are your conclusions? · What do you infer from the statistical analysis? · State the interpretations in non-technical terms. What information might lead to a different conclusion? · Are there any variables missing? · What additional information would be valuable to help draw a more certain conclusion?

QNT561_r9_Part_3_Inferential_Statistics_Week_6.doc Title ABC/123 Version X 1 Part 3 Inferential Statistics QNT/561 Version 9 2 Part 3: Inferential Statistics Option 1: Manufacturing Database 1. The National Association of Manufacturers (NAM) contracts with your consulting company to determine the estimate of mean number of production workers. Construct a 95% confidence interval for the population mean number of production workers. What is the point estimate? How much is
- 4. the margin of error in the estimate? 2. Suppose the average number of employees per industry group in the manufacturing database is believed to be less than 150 (1000s). Test this belief as the alternative hypothesis by using the 140 SIC Code industries given in the database as the sample. Let α = .10. Assume that the number of employees per industry group are normally distributed in the population. 3. You are also required to determine whether there is a significant difference between mean Value Added by the Manufacturer and the mean Cost of Materials in manufacturing using alpha of 0.01. 4. You are requested to determine whether there is a significantly greater variance among values of Cost of Materials than of End-of-Year Inventories. Option 2: Hospital Database 1. As a consultant, you need to use the Hospital database and construct a 90% confidence interval to estimate the average census for hospitals. Change the level of confidence to 99%. What happened to the interval? Did the point estimate change? 2. Determine the sample proportion of the Hospital database under the variable “service” that are “general medical” (category 1). From this statistic, construct a 95% confidence interval to estimate the population proportion of hospitals that are “general medical.” What is the point estimate? How much error is there in the interval? 3. Suppose you want to “prove” that the average hospital in the United States averages more than 700 births per year. Use the hospital database as your sample and test this hypothesis. Let alpha be 0.01. 4. On average, do hospitals in the United States employ fewer
- 5. than 900 personnel? Use the hospital database as your sample and an alpha of 0.10 to test this figure as the alternative hypothesis. Assume that the number of births and number of employees in the hospitals are normally distributed in the population. Option 3: Consumer Food 1. Suppose you want to test to determine if the average annual food spending for a household in the Midwest region of the U.S. is more than $8,000. Use the Midwest region data and a 1% level of significance to test this hypothesis. Assume that annual food spending is normally distributed in the population. 2. Test to determine if there is a significant difference between households in a metro area and households outside metro areas in annual food spending. Let α = 0.01. 3. The Consumer Food database contains data on Annual Food Spending, Annual Household Income, and Non-Mortgage Household Debt broken down by Region and Location. Using Region as an independent variable with four classification levels (four regions of the U.S.), perform three different one- way ANOVA's—one for each of the three dependent variables (Annual Food Spending, Annual Household Income, Non- Mortgage Household Debt). Did you find any significant differences by region? Option 4: Financial Database 1. Use this database as a sample and estimate the earnings per share for all corporations from these data. Select several levels of confidence and compare the results. 2. Are the average earnings per share for companies in the stock market less than $2.50? Use the sample of companies represented by this database to test that hypothesis. Let α = .05.
- 6. 3. Test to determine whether the average return on equity for all companies is equal to 21. Use this database as the sample and α = .10. Assume that the earnings per share and return on equity are normally distributed in the population. 4. Do various financial indicators differ significantly according to type of company? Use a one-way ANOVA and the financial database to answer this question. Let Type of Company be the independent variable with seven levels (Apparel, Chemical, Electric Power, Grocery, Healthcare Products, Insurance, and Petroleum). Compute three one-way ANOVAs, one for each of the following dependent variables: Earnings Per Share, Dividends Per Share, and Average P/E Ratio. Copyright © XXXX by University of Phoenix.

Your assignment is to analyze ONE of the following databases: · Manufacturing · Hospital · Consumer Food · Financial Select one of the databases based on the information in the Signature Assignment Options.
- 16. Provide a 1,600-word detailed, statistical report including the following: · Explain the context of the case · Provide a research foundation for the topic · Present graphs · Explain outliers · Prepare calculations · Conduct hypotheses tests · Discuss inferences you have made from the results This assignment is broken down into four parts: · Part 1 - Preliminary Analysis · Part 2 - Examination of Descriptive Statistics · Part 3 - Examination of Inferential Statistics · Part 4 - Conclusion/Recommendations Part 1 – Preliminary Analysis (3 – 4 paragraphs) Generally, as a statistics consultant, you will be given a problem and data. At times, you may have to gather additional data. For this assignment, assume all the data is already gathered for you. · State the objective. · What are the questions you are trying to address? · Clearly and in sufficient detail, describe the population in the study. · What is the sample? · Discuss the types of data and variables. Are the data quantitative or qualitative? · What are levels of measurement for the data? Part 2 – Descriptive Statistics (3 – 4 paragraphs) · Examine the given data. · Present the descriptive statistics (mean, median, mode, range, standard deviation, variance, CV, and five-number summary).
- 17. · Identify any outliers in the data. · Present any graphs or charts you think are appropriate for the data. Note: Ideally, we want to assess the conditions of normality too. However, for the purpose of this exercise, assume data is drawn from normal populations. Part 3 – Inferential Statistics (2 – 3 paragraphs) Use the Part 3: Inferential Statistics document. · Create (formulate) hypotheses · Run formal hypothesis tests · Make decisions. Your decisions should be stated in non- technical terms. Hint: A final conclusion saying “reject the null hypothesis” by itself without explanation is basically worthless to those who hired you. Similarly, stating the conclusion is false or rejected is not sufficient. Part 4 – Conclusion and Recommendations (1 – 2 paragraphs) · What are your conclusions? · What do you infer from the statistical analysis? · State the interpretations in non-technical terms. What information might lead to a different conclusion? · Are there any variables missing? · What additional information would be valuable to help draw a more certain conclusion?

Identify the population served, ownership, types of services provided; indicate affiliations with managed care organizations, payer sources. Address other characteristics consistent with course objectives (see below).
- 20. You may select a hospital in the area where you live, or you may pick another organization. Think about this assignment as you read this week's chapter and lecture notes, participate in the discussions. During Week 3, pick the hospital you will profile so you'll have time to collect your information and prepare your paper for submission in Week 4. Hospital Characteristics Some questions to consider as you prepare your paper: - Who owns the hospital? - What is the history of the organization? - What are the stated mission and vision of the hospital? - Is this a for-profit, not-for-profit, or governmental hospital? Is it church-affiliated? - What type of services do they provide? - Are there any ratings on the hospital or services? (Blog?) - What are the primary forms of funding for the hospital? - Is the hospital part of a network or a health system? - What managed care affiliations does the hospital have? - What is the composition of the Board of Directors, and how are they appointed? - How many Medical Staff Members are there, and what types of doctors are represented? - Does the hospital have a foundation? - What community education does it offer? - Is the hospital well known for any special service or program? - What types of jobs are currently available at the hospital? What are some of the most frequent openings? - What are the hospital's strategic planning objectives for the year ahead? Do not feel that you need to answer all of these questions for the hospital which you are studying, but using as many of these
- 21. questions as possible will help you to prepare a very good profile. You will also be applying key course concepts in the process of writing this paper. Good luck, and enjoy learning more about a "real world" hospital.
