SPSS Problem Set 4

Problem 1

– Write a brief explanation of the difference between one sample and two sample hypothesis testing.

Problem 2: Use the General Social Security Full Time data set (gssft.sav) to complete the following problem. (pic attached)

Test the hypothesis that for all full-time workers, the population value for average hours worked is 40 hours (variable hrs1). You will use the one-sample t-test. (pic attached)

1. What assumptions need to be met to use the one-sample t test? Do you think the data meet the assumptions?

2. What is the null hypothesis that you want to test? The alternative hypothesis?

3. Test the hypothesis, and write a brief summary of your conclusions.

4. Based on the 95% confidence interval for the mean difference, can you reject the null hypothesis that the average population value for hours is 43 hours? Explain.

Problem 3: t-test of means (two variables: testing sample measures as proxy for population in comparison to one another)

Use the Country dataset (country.sav) to complete the following problem. Test the hypothesis that the average life expectancy for males is the same as the average life expectancy for females (variables: lifeexpm and lifeexpf).

1. What is the null hypothesis? What is the alternative hypothesis?

2. Look at the distribution of the differences. Summarize your conclusions and state whether there is a statistical difference in life expectancies.

Problem 4 Use the 04 Cars (04cars.sav) dataset. Compute a new variable called markup = ((suggretail-dealercost)/dealercost)*100. You will use the “Transform>Compute Variable” dialog. You will test the hypothesis that Sports Cars have a higher markup than other cars.

1. Formulate the null hypothesis that you want to test. The alternative hypothesis?

2. Which type of t-test will be used to evaluate your hypothesis? Why are you choosing this method?

3. Test the hypothesis at a 95% confidence level and write a brief summary of your conclusions.

Problem 5 Testing of independent statistics (i.e., means) as proxies to population measures Use the School Salary data set (schoolsalary.sav). You are asked to investigate if male and female school superintendents earn the same pay? Salaries for 20 males and 17 females in a certain metropolitan area are given in the school salary dataset. At α = .01, were the mean superintendent salaries greater for men than for women?

1. State both hypotheses (Ho and Ha).

2. State the decision rule and sketch it as a bell curve diagram.

3. Conduct an independent t-test of the above hypothesis and state your findings.

After completing the problems:

– Copy the relevant SPSS output to a MS Word document. (You can simply copy and paste)

– Add your analytic comments to each problem prior to the SPSS output which it supports.

– Clearly number and label each problem in the document.

Forensic Response And Investigation Plan

Forensic Response And Investigation Plan.

STEP 3: Write A Forensic Response And Investigation Plan The GCU board has reviewed your response readiness plan and heard reports from business managers on the impacts of a network attack. Based on the information you provided, the managers of the GCU branches identified the consequences from the recent network attack, including the stoppage of workflow and ability to meet customer requests, a stoppage in communications (e-mail and web requests), and the loss of business credibility and public confidence. They are concerned that legal expenses may be incurred as part of the damage mitigation for this incident. Alarmed at the magnitude of these impacts, the board of directors asks you to report on how this attack may have happened, so the organization can do everything within its power to prevent similar attacks in the future.

The use of computers and electronic devices to aid in the commission of crimes has seen explosive year-over-year growth. The risk/reward potential for criminals in this environment is high compared to many other types of crimes. One tool of choice for criminals is malware, whether for theft of personal information, computing resources, or other forms of mischief. Most organizations cease their effort once they have removed a malware threat or removed an infection. The trend in malware is toward memory-resident payloads, often with little or no footprint beyond active memory, creating a complex situation where a minor slip-up can ruin any chance at proper analysis. Obtaining malware artifacts from the wild is an elite skill that very few people possess, particularly when it is memory-based. Malware forensics uses digital forensic tools and techniques, including using imaging programs to analyze compromised resources, the application of imaging and verification procedures on user accounts, and using e-mail forensics and encryption forensics to answer key questions. Organizations that outsource the storage of large volumes of data may require cloud/GIS forensics and/or analysis of third party applications when bring-your-own-device (BYOD) practices are in effect. The forensic response and investigation plan should apply best practices in digital forensics to guide the GCU leadership in effectively responding to a future incident. Your goal in constructing this plan is to go much further than your original analysis and explain in detail how to perform a full malware analysis of the incident.

The last 100 years of European history.

The last 100 years of European history..

Analyze the last 100 years of European history, explaining how Europe (and in many respects, the world itself) has turned out like it has in our current day. This is not some random, sprawling essay, no matter how it appears to you, nor is it merely a chronology of events. The essay MUST BE based on and around the “isms” which, as you know, is the centerpiece of this course. Modern-day events that could be useful for you in providing examples of the impact of the “isms” include North Korea issues, rising nationalism in Europe, Middle East issues (such as ISIS, Syrian civil war, Syrian refugee crisis), economic challenges in Southern Europe, Brexit and the EU, or Ukrainian issues with Russia (there are other examples). In the end, you will want to build an analysis that will show how all of our modern-day issues are built out of decisions and choices from the previous years…in particular post-French Revolution and World War I. In the last half of the class, we have studied the world reeling from the mid-1850s that led to radical changes in the 1920s & 1930s leading to yet another massive war, World War 2. From there, Europe and the world has continued to deal in the aftermath of the decisions created in the early part of the 20th Century—choices about governing styles, economic strategies, ways of living, impacts of technology, and nationalism or globalism. Our discussions and assignments can help you—we started first noting how the 30 Years War was the beginning of the modern age. Note that when it finished, 1648, Hobbes had already written his main work, Leviathan. Just a few decades later, John Locke would stake out more ground about the issue of social contract. Our class shifted next to investigate the impact of the French Revolution, a critical point in modern European history. We talked then about trends from the Revolution such as liberalism and nationalism, critical steps on this issue of rights. As we moved toward the end of the 19th century, we looked at the emergence of socialism and events in Central Europe, and how individual liberty or economic equity was increasingly becoming the focus of the country. The development of Germany in 1870 became something of a focal point in that question, leading ultimately to the disaster of World War I. The post-Versailles world, then, was struggling with this same question of rights—what are the rights of humans? Does the human have the right to make as much money as they can? Or, are they limited by the concerns for economic equity? Is one culture of humans more advanced than another culture of humans? Should the advanced culture try to help the other culture? How should the government protect my rights? Can the government protect my rights while embracing socialism? Those questions ultimately led us to World War II and our final discussions. Those last discussions noted the ascension of Marx’s version of socialism or economic equity (or the English version proclaimed by John Maynard Keynes) in much of the world and how that contributed to the Cold War. Here, then, is the focus for your essay. Remember, you are addressing this: “Analyze the last 100 years of European history, explaining how Europe (and in many respects, the world itself) has turned out like it has in our current day.” First, explain HOW the “isms” set up the experience of the 20th century. This analysis should at least touch on the impact of the French Revolution in creating the atmosphere for the “isms.” This should take you about 2 pages. Second, develop your analysis on the impact to our modern time. This is the bulk of the essay, 3-4 pages. This is where you should use events of the 20th century (things we studied) as well as modern day issues as parts of your analysis. Modern day issues from the past 10 years that connect well here include, but are not limited to: North Korean Crisis, Immigration crisis in Europe, ISIS, Israel-Palestine, European economic crisis, Brexit, Russia vs Ukraine, rise of China, war on terror, Middle East Islam issues (Turkey, Kurds, Iran, Saudi Arabia), world trade tensions. Third, write a conclusion that provides your view of the coming 25-50 years; how will the “isms” continue to haunt us or guide us. This will be at most a page, but could be done well in a developed paragraph. So, you can see the essay as both “what did you learn in the second half of the course (WW1 to present day)” AND “how did those things emerge from the isms of the 19th century.” I want to see that you understand, can see and can analyze the course of history, the patterns or lessons of history as mentioned in Course Outcome #5. Thus, this essay is dealing primarily with Course Outcome #5 on detecting the lessons of history and Outcome #2 on the thematic historical influences, while using the knowledge from Outcome #1 and historical method from Outcome #6 (and of course “college level writing,” Outcome #7). Consult the syllabus to read these outcomes in greater depth. This should be a 5-7 page essay that demands solid writing based on good historical research (3-5 sources would be best). All citations must be done in the Chicago Style Guide, the citation type for History as a discipline. You SHOULD include a list of your sources on a separate page (that page is NOT part of the 5-7 pages). A cover page is NOT required. This assessment MUST be typed (11 or 12 point font; Times or Calibri is best), 1.5 spacing and possess good grammar, spelling, and a clear, organized thought-process
