The Livewright Medical Supplies Company has a total of 12 salespeople it wants to assign to
three regions – the South, the East, and the Midwest. A salesperson in the South earns $600 in
profit per month of the company, a salesperson in the East earns $540, and a salesperson in the
Midwest earns $375. The southern region can have a maximum assignment of 5 salespeople.
The company has a total of $750 per day available for expenses for all 12 salespeople. A
salesperson in the South has average expenses of $80 per day, a salesperson in the East has
average expenses of $70 per day, and a salesperson in the Midwest has average daily expenses
of $50. The company wants to determine the number of salespeople to assign to each region to
maximize profit.
Formulate an integer programming model for this problem
Solve this model by using the computer.
Solve the following mixed integer linear programming model by using the computer:
MaximizeZ=5x1 +6x2 +4x3
Subject to
5x1 +3x2 +6x3 ≤20
x1+3x2 ≤12x1, x3 ≥ 0x2 ≥ 0 and integer
3. The Texas Consolidated Electronics Company is contemplating a research and development
program encompassing eight research projects. The company is constrained from embarking on
all projects by the number of available management scientists (40) and the budget available for
R&D projects ($300,000). Further, if project 2 is selected, project 5 must also be selected (but
not vice versa). Following are the resource requirements and the estimated profit for each
project.

Formulate the integer programming model for this problem and solve it using the computer.
4. During the war with Iraq in 1991, the Terraco Motor Company produced a lightweight, all-
terrain vehicle code-named “J99-Terra” for the military. The company is now planning to sell
the Terra to the public. It has five plants that manufacture the vehicle and four regional
distribution centers. The company is unsure of public demand for the Terra, so it is considering
reducing its fixed operating costs by closing one or more plants, even though it would incur an
increase in transportation costs. The relevant costs for the problem are provided in the
following table. The transportation costs are per thousand vehicles shipped; for example, the
cost of shipping 1,000 vehicles from plant 1 to warehouse C is $32,000.

Walden University SPSS Worksheet
Part 1
To prepare for this Part 1 of your Assignment:
Review this week 9 and 10 Learning Resources and media program related to multiple regression.
Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week.
Based on the dataset you chose, construct a research question that can be answered with a multiple regression analysis.
Once you perform your multiple regression analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.
Write a 1- to 2-page analysis of your multiple regression results for each research question. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.
Then
Review Warner’s Chapter 12 and Chapter 2 of the Wagner course text and the media program found in this week’s Learning Resources and consider the use of dummy variables.
Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in this week’s Learning Resources.
Consider the following:
Create a research question with metric variables and one variable that requires dummy coding. Estimate the model and report results. Note: You are expected to perform regression diagnostics and report that as well.
Once you perform your analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.
Write a 2- to 3-page analysis of your multiple regression using dummy variables results for each research question. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.

Walden Week 4 Probability Sampling Distributions and Confidence Intervals Questions
In your Week 2 Assignment, you displayed data based on a categorical variable and continuous variable from a specific dataset. In Week 3, you used the same variables as in Week 2 to perform a descriptive analysis of the data. For this Assignment, you will calculate a confidence interval in SPSS for one of the variables from your Week 2 and Week 3 Assignments.To prepare for this Assignment:Review the Learning Resources related to probability, sampling distributions, and confidence intervals.For additional support, review the Skill Builder: Confidence Intervals and the Skill Builder: Sampling Distributions, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you chose) from Week 2.Choose an appropriate variable from Weeks 2 and 3 and calculate a confidence interval in SPSS.Once you perform your confidence interval, review Chapter 5 and 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Assignment:Write a 2- to 3-paragraph analysis of your results and include a copy and paste of the appropriate visual display of the data into your document. If you are using the Afrobarometer Dataset, report the mean of Q1 (Age). If you are using the HS Long Survey Dataset, report the mean of X1SES.Based on the results of your data in this confidence interval Assignment, provide a brief explanation of what the implications for social change might be
