# Option 1: Manufacturing Database ; Write a 1,600-word detailed, statistical report including the following: Due Friday 20:00 Eastern

**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

**Use the following scenario for the assignnment**. (**Option 1: Manufacturing Database)**

This database contains six variables taken from 20 industries and 140 subindustries in the United States. Some of the industries are food products, textile mill products, furniture, chemicals, rubber products, primary metals, industrial machinery, and transportation equipment. The six variables are Number of Employees, Number of Production Workers, Value Added by Manufacture, Cost of Materials, End-of-Year Inventories, and Industry Group. Two variables, Number of Employees and Number of Production Workers, are in units of 1000. Three variables, Value Added by Manufacture, Cost of Materials, and End-of-Year Inventories, are in million-dollar units. The Industry Group variable consists of numbers from 1 to 20 to denote the industry group to which the particular subindustry belongs.

**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?

**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
- 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?

**Format** your assignment consistent with APA format.
