State both hypotheses (Ho and Ha).

Problem 1

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

Problem 2: T-test of means (one variable: testing sample measure as proxy for population)

Use the GSSFT (General Social Security Full Time) data set to complete the following problem.

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.

a) What assumptions do you need to use the one-sample t test? Do you think the data meet the assumptions?

b) What is the null hypothesis that you want to test? The alternative hypothesis?

c) Test the hypothesis and write a brief summary of your conclusions.

d) 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 means (two variables: testing sample measures as proxy for population in comparison to one another)

Use the Country data set 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). Use the paired samples t-test.

a) What is the null hypothesis? What is the alternative hypothesis?

b) 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 04cars 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.

a) Formulate the null hypothesis that you want to test? The alternative hypothesis?

b) Which type of t-test will be used to evaluate your hypothesis? What are you choosing this method?

c) Test the hypothesis and write a brief summary of your conclusions.

Problem 5

Use the School Salary data set. 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? Note that the gender variable is called male and is coded 0,1 (0 indicating female and 1 indicating male, using the coding protocol 0 is not and 1 is.)

(a) State both hypotheses (Ho and Ha).

(b) State the decision rule and sketch it as a bell curve diagram.

(c) Conduct an independent T-test of the above hypothesis and state your findings.

After completing the problems:

1. Copy the relevant SPSS output to a MS Word document. (You can simply copy and paste or you can export the file while in SPSS.)

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

3. Clearly number and label each problem in the document.

4. Submit your assignment by uploading it to this site.

Although many health care organizations use the same equipment; employ similar personnel; and have standard procedures, protocols, and processes, no two organizations will have the same information technology (IT) infrastructure. This difference among IT infrastructures is attributable to varying policy decisions, procedures, system designs, budgets, and organizational cultures. So you can be an effective nurse informaticist, it is critical that you are very familiar with the IT infrastructure at your own organization and are aware of the reasoning behind it. Being conversant on the system enables you to more effectively work within the system and to better promote the appropriate HIT tool.
In your Practicum experience, you have been familiarizing yourself with a health care organization and its IT infrastructure, as well as with how data and information are handled within the organization. For this Discussion, you provide a brief summary of your findings.
To prepare:

• Identify the relevant features of the IT infrastructure of the organization. (ANY HEALTHCARE ORGANIZATION)
• Consider the strengths and weaknesses of the IT infrastructure.
• Reflect on the current role of nursing informatics in this organization and how it could be strengthened.

THEN

Post a brief description of your Practicum site (ANY HOSPITAL WITHOUT NAMING THEM). Then, describe the IT infrastructure at this site, assessing its strengths and weaknesses. Explain the role of nursing informatics within this organization and how the role could be strengthened.

Write a 5–7-page analysis on a featured debate on learning theory. You will explore how the evolution of learning theories and neuroscience has shaped a current learning controversy.
Learning theories evolve over time. It is important to understand how historical, political, and cultural changes affect learning theories and how we apply them. The purpose of analyzing a current learning theory debate allows you to demonstrate your knowledge of theories, critical thinking skills, and how to apply theory to your own specialized field of psychology.
By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:

• Competency 1: Evaluate the strengths, limitations, and applications of the foundational learning theories.
  • Explain how the evolution of learning theories and neuroscience over time has shaped a selected learning controversy.
  • Evaluate multiple perspectives on the selected learning controversy.
• Competency 3: Apply evidence based research in learning theories to guide decision making and problem solving.
  • Assess the implications of this learning controversy on your area of specialization.
• Competency 4: Communicate in a manner that is scholarly, professional, and consistent with expectations for members of the psychological professions.
  • Write clearly and logically, with correct use of spelling, grammar, punctuation, and mechanics; format paper, citations, and references using APA style. I will upload instructions and grading score guide in the morning.

Preparation

Learning theories evolve over time. As we discover more about how people learn, the application of learning theories also changes. An idea that worked 50, 20, or even 5 years ago might not work currently due to a shift in cultural beliefs, new knowledge, or new learning contexts. Anytime there is a change in our thinking it can impact the way we apply learning theories. Many times differing perspectives can lead to productive discussions and academic debates that further the evolution of the learning theory.

Instructions

In this assessment, you will explore how the evolution of learning theories and neuroscience has shaped a current learning controversy.
Select one of the following learning controversies:

• Howard Gardner’s Multiple Intelligences Theory.
• Learning Styles.
• Brain Hemisphere Dominance (Left verses Right Brain).

Research the historical approaches for the learning controversy and how this issue is currently being debated.

• Looking at this learning controversy through the lens of learning theories and neuroscience, what has changed or been discovered that has led to this debate?
• Analyze the multiple perspectives of the selected learning controversy.
• What are the arguments and priorities for this issue?
• Assess the impact of the selected learning controversy on your area of specialization.

Make sure to include the following:

• Explain how the evolution of learning theories and neuroscience over time has shaped selected learning controversy.
• Evaluate multiple perspectives to the selected learning controversy.
  • What are arguments and priorities of the proponents and critics of this issue?
• Assess the implications of this learning controversy on your area of specialization.

Additional Requirements

• Length: 5–7 pages (not counting your title page or references), double-spaced, 12-point font.
• Number of references: Minimum of 5 references.
• Article distinctions: There are three different types of articles. Research articles present original research, review articles discuss research already presented elsewhere, and survey articles are comprehensive review articles that discuss an entire field or area of research. References to books are acceptable, but they should be kept to a minimum—probably no more than five.
• APA style: You must use proper APA style to cite and list your references. Refer to the Writing Center’s APA Style and Format guidelines (linked in the Suggested Resources) for more information.
• Format: Use the following structure:
  • Cover page (your name, your specialization or program, title and course number, current quarter and year, and instructor’s name).
  • Abstract (optional).
  • Body of paper, including headings and subheadings over the appropriate content.
  • Reference list.
  • Refer to the APA Style and Format guidelines for additional formatting information.
• Style: Write in the third person as an impartial narrator. Avoid the use of I, we, or you. In particular, avoid phrases like “I think” in favor of phrases like “the evidence suggests” or “research indicates.” In science, personal opinion carries no weight unless supported by a combination of empirical research and statistical or logical-mathematical inference.
• Other notes: Avoid long quoted passages from your source texts. Your writing should be a synthesis of your own ideas, in your own words—even if your ideas refer to the original ideas of others, in which case the references should be explicit. Graduate-level writing should be scholarly and more than a mere summary. It should present a unique thesis or at least a significant point you are trying to make, adding appreciably to what is already known of your topic. Your point or thesis will stand or fall solely on its strength—that is, the quality and quantity of the evidence you present.
