What are the minimum capacity changes at Glasgow that will alter the optimum set of routes and what will those alterations be? Explain how you arrive at each one of your answers.

Linear Programming

Paint Transhipment Problem
A company has two factories, one each at Bristol and Leeds. The factories produce paints which are sold to five wholesalers.
A. Formulate a linear programming model to determine the minimum cost transportation schedule.
Explain clearly the variables you use and the constraints you construct. What is the minimum cost transportation schedule and what are the corresponding costs?
B. Discuss the effect on the minimum transportation cost when capacity at each factory or warehouse is altered by adding or subtracting one ton. What are the minimum capacity changes at Glasgow that will alter the optimum set of routes and what will those alterations be? Explain how you arrive at each one of your answers.
C. The management of the company is considering the possibility of closing down one of the warehouses as this is expected to result in substantial labour and maintenance savings. Further, the manager of the Birmingham warehouse is considering sub-letting some of the capacity of this warehouse. Such sub-lets would have to be in exact multiples of 1000 tons. It is estimated that each 1000 tons of capacity could be let for £21,000 per week. Formulate a mixed integer linear programming model – or, if necessary, different model variants – to examine and evaluate the alternative courses of action. What would you recommend the company to do, and why?
Discuss the alternatives, also taking into account the solution from part (a) and explain which additional information you might need to give the company more specific advice.

Discuss how the three GEOINT components are applied to a military, civilian, or commercial intelligence problem-set or scenario. This should be an actual intelligence problem that is of concern to the Intelligence Community.

Below are the definitions for the three components of GEOINT:

The technical, geographic, and intelligence information derived through the interpretation or analysis of imagery and collateral materials.
Information that identifies the geographic location and characteristics of natural or constructed features and boundaries on the earth, including: statistical data; information derived from, among other things, remote sensing, mapping, and surveying technologies; and mapping, charting, geodetic data, and related products.1
Discuss how the three GEOINT components are applied to a military, civilian, or commercial intelligence problem-set or scenario. This should be an actual intelligence problem that is of concern to the Intelligence Community. If in doubt, please ask before you begin writing.

Review your classmates’ posts and respond to at least one in a minimum of 150 words. Explain why you agree or disagree. Then, share an example from your professional experience to support your assertions.

In the text, Frankfort-Nachmias and Leon-Guerrero discuss the process of constructing a research question and hypotheses.

Review How to Extract GSS Data to Excel or How to Extract Data to Excel Using the Library to find statistical data to choose a mock study topic you will explore throughout the course. You must choose either GSS data or data in the University Library and state the name of the dataset in this forum to receive credit. You will continue to use this data throughout the entire course, so be sure to take some time to properly choose and download the data this week.

Write a 250- to 300-word response to the following:

State whether the data you have chosen to work with originated in the GSS site or in the University Library. If a dataset was chosen from the library data, you must state the specific location and dataset you extracted.
Choose and list at least three variables , along with the associated survey question and response choices.
Create a research question using all three of your variables.
Review your classmates’ posts and respond to at least one in a minimum of 150 words. Explain why you agree or disagree. Then, share an example from your professional experience to support your assertions.

Do you suspect the relation is positive or negative? Why? Which would be considered the independent variable, which the dependent variable? Why?

Look back to the raw data you collected in week 1. There are 7 variables listed:

Vehicle type/class

Year

Make

Model

Price

MPG (city)

MPG (highway)

Choose TWO variables that you feel are correlated and explain why you feel that they are correlated. Do you suspect the relation is positive or negative? Why? Which would be considered the independent variable, which the dependent variable? Why?

Run a regression analysis in Excel and provide the results in your post along with your raw data. Looking at the R2 value, explain what this indicates about the strength of the relation. Then write out your Regression Equation, state if your p-value and conclusion.

 

Discuss specific challenges associated with “people” research.

Instructions
Using your O’Sullivan readings (Chapters 6-7), respond to the following:
In 1-2 paragraphs, discuss specific challenges associated with “people” research.
Practically, how can these challenges be worked around or avoided?
Complete the following exercises from your Salkind text. None of the questions this week require the use of SPSS. Save all of your work as one single Word file and upload it for grading. Show your work when required.
Chapter 7, “Time to Practice” questions 3, 5, and 6
Chapter 8, “Time to Practice” questions 1, 5, and 9
All questions must be clearly labeled. Answers that are not clearly labeled will not receive credit.

Plan and describe how you will summarise the socio-demographic and general health of the sample (descriptive statistics).

Step 1:
Get to know your data. Look at the variables and see what they are measuring and what types of data you have to analyse.
Step 2:
Plan and describe how you will summarise the socio-demographic and general health of the sample (descriptive statistics). Think about the following points: What summary statistics will you use for which kinds of data? What data will you put in tables and/or graphs? How will you assess the suitability of each of these methods? What assumptions are they based on? How will you treat each variable?
What are the sociodemographic, health and lifestyle characteristics of your sample participants? Describing your sample is the first part of your analysis and comes first in the report results. Think about why it is important to get a description of the sample before you present results from hypothesis testing.
Step 3:
Develop a series of hypotheses that can be tested using the different types of statistical tests below. What would be the hypotheses? What tests will you do and why? Explain why the statistical techniques that you will use are appropriate. (Hint: weeks 3-10). If you decide to create new variables, describe how you will do so and why you chose each method of doing so. (Hint: see information in weeks 1-4)
Select two categorical variables that are of interest to you and perform an appropriate univariate statistical test. Explain why the statistical test that you have used is appropriate, show the results and report your conclusion. Repeat this again using two new categorical variables or one new outcome (dependent) variable for the same potential explanatory (independent) variable.
Select a variable with two or three categories and investigate how the values of another continuous (scale) variable differ between categories. You may choose to create a new variable with two, three, or more categories from an existing continuous or categorical variable. (Example: blood pressure and gender or blood pressure and BMI categorised as normal, overweight, obese.) Repeat this again with another pair of variables that will lead to a nonparametric test if possible. (Hint: explore the data to look for skewed distributions of a continuous variable).
Perform a multiple linear regression analysis to find those independent variables (continuous and categorical) that are significantly related to systolic blood pressure at the 5% significance level.
Use Enter method to add potential risk factors.

Some potential research questions for this assignment

Choose a research question that you find interesting. The following are just suggestions you do not have to choose one of them. Indeed, I encourage you to develop your own original research question (and there is an extra 2 marks for this). The more interesting the question is for you, the more fun the assignment will be:
