Stats 1 Assignment

The purpose of the statistics project is to go through the process that a statistician goes through when analyzing new data. You will be asked to do some Exploratory Data Analysis, describe the data using descriptive statistics and plots, answer some questions about probability of future information, create confidence intervals, and describe relations of the data through the use of correlations and linear regressions.

For this project you will use StatCrunch (or any other software you are comfortable using.). You will use the data from the StatCrunch Website entitled “Sample College Data.” This is data sampled from universities from a few states on the East Coast and you will use it to work through the sections below. To find the data follow the link to StatCrunch from MyMathLab. In the Data box click the link to “Data sets” and use the search bar to find the data set “Sample College Data”, then open StatCrunch.

Section 1 Exploratory Data Analysis: In this section of your analysis you will need to open the data, describe the data by data type, understand the sample size, the number of data points for each row etc.

· Think about displaying the categorical (qualitative data) using pie charts or bar charts

· For numerical (quantitative) look to show the data using histograms or other appropriate plots.

For every plot or piece of information about the data you uncover, please summarize what the plots/information says about the “shape” of the data.

Section 2 Descriptive Statistics: In this section you will describe the data using methods we learned for qualitative and quantitative data. This includes frequencies, measures of central tendency, measures of dispersion and any other statistics you may find within the data (percentiles, outlies, etc.).

For all descriptive statistics that you find ensure that you summarize each and how/what is describes in the data.

Section 3 Probabilities: In this section you will find the probability of several possible outcomes listed below. You will need to use the data to create these probabilities.

1. Find the probability that a randomly selected university will be public.

2. Find the probability that a randomly selected university will have an Admissions rate equal to 70% but less than 80%.

3. Find the probability that a randomly selected university will have an admissions rate below 60% given that it is a private institution.

Section 4 Confidence Intervals: In this section you will need to construct 95% Confidence intervals of the mean and variance of all the numerical (quantitative) data. For each please interpret the confidence interval and explain any surprising results.

Section 5 Hypothesis Testing: In this section you will make some hypotheses about the data and then use what we learned in lecture/homework to test these hypotheses.

1. Is the average Admissions Rate greater than 70?

2. Is the average Retention Rate less than 80?

3. Is the average Graduation Rate equal to 55?

4. Is the average Admissions Rate for Private universities the same as that for Public?

Section 6 Correlation and Regression: In this section you will calculate the correlation matrix and discuss any interesting findings or expected findings. You will also build a regression model and compare the coefficients to the correlation matrix.

1. Calculate the correlation matrix for the qualitative columns.

2. Build a regression model that takes the dependent variable Admissions Rate:

a. Do a simple linear regression with SAT Reading as the independent variable. 

b. Do a simple linear regression with Average Financial Aid as the independent variable. 

c. Compare the two above outputs to the correlation matrix entries and discuss what you see.

3. Build a regression model that takes the Variable Graduation Rate:

a. Repeat a-c from part 2 and discuss the results.

Project Deliverable 4: Infrastructure and Security

Due Week 8 and worth 150 points

This assignment consists of two (2) sections: an infrastructure document and a revised Gantt chart or project plan. You must submit both sections as separate files for the completion of this assignment. Label each file name according to the section of the assignment for which it is written. Additionally, you may create and / or assume all necessary assumptions needed for the completion of this assignment.

The last section of the project plan will present the infrastructure in accordance with the parameters set forth at the outset of the project. The network solution that is chosen should support the conceived information system and allow for scalability. The network infrastructure will support organizational operations; therefore, a pictorial view of workstations, servers, routers, bridges, gateways, and access points should be used. In addition, access paths for Internet access should be depicted. A narrative should be included to explain all the nodes of the network and the rationale for the design. Lastly, using the Confidentiality, Integrity and Availability (CIA) Triangle, define the organizational security policy. CIA is a widely used benchmark for evaluation of information systems security.

Section 1: Infrastructure Document

1. Write a five to ten (5-10) page infrastructure document in which you:

a. Design a logical and physical topographical layout of the planned network through the use of graphical tools in Microsoft Word or Visio, or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length.

b. Illustrate the possible placement of servers including access paths to the Internet and firewalls. Note: Facility limitations, workstations, printers, routers, switches, bridges and access points should be considered in the illustration.

c. Explain the rationale for the logical and physical topographical layout of the planned network.

d. Create a comprehensive security policy for the company that will:

i. Protect the company infrastructure and assets by applying the principals of CIA. Note: CIA is a widely used benchmark for evaluation of information systems security, focusing on the three core goals of confidentiality, integrity and availability of information.

ii. Address ethical aspects related to employee behavior, contractors, password usage, and access to networked resources and information.

Your assignment must follow these formatting requirements:

  • Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
  • Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
  • Include charts or diagrams created in MS Visio or Dia as an appendix of the infrastructure document. All references to these diagrams must be included in the body of the infrastructure document.

Section 2: Revised Gantt Chart / Project Plan

Use Microsoft Project or an open source alternative, such as Open Project, to:

2. Update the Gantt chart or project plan (summary and detail) template, from Project Deliverable 3: Database and Programming Design, with all the project tasks.

The specific course learning outcomes associated with this assignment are:

  • Demonstrate an understanding of existing and emerging information technologies and strategic impact on organizational operations.
  • Evaluate the issues and challenges associated with information technology integration.
  • Evaluate the ethical concerns that information technology solve or present in a global context.
  • Use technology and information resources to research issues in information technology.
  • Write clearly and concisely about strategic issues and practices in the information technology domain using proper writing mechanics and technical style conventions.

Grading for this assignment will be based on answer quality, logic/organization of the paper, and language and writing skills, using the following rubric found here.

My Original project was based on a company named bicycle trader which essentially was very similar to “Ebay” in its function, if that’s relevant.

  1. The personnel director of a firm has developed two tests to help determine whether potential employees would perform successfully in a particular position. To help estimate the usefulness of the tests, the director gives both tests to 43 employees that currently hold the position. Table 5 gives the scores of each employee on both tests and indicates whether the employee is currently performing successfully or unsuccessfully in the position. If the employee is performing successfully, we set the dummy variable Group is set equal to 1; if the employee is performing unsuccessfully, we set Group equal to 0. Let x1 and x2 denote the scores of a potential employee on tests 1 and 2.

Perform a discriminant analysis on the data and interpret the result, including the confusion matrix. Include all required steps in assessing the final model. By trial and error, find the threshold, which minimizes prediction relative error.

Plant Chemical Adaptations 

Physical adaptations are one way plants have become well-adapted to specific environmental conditions. For example, cacti have spines in place of leaves to prevent water loss in the arid conditions of the desert, and deciduous trees lose their leaves in the fall to survive cold weather conditions over the winter. Chemical adaptations are another means for plant protection. Many plants produce toxic or noxious compounds to protect themselves from insects or animals that would eat them, to reduce competition from other plants, or even to change the response of pollinators. Humans analyze and harvest these compounds for our own benefit.

Read this article on the search for useful plant compounds: Mother Nature’s Medicine Cabinet

Read this article on the less-than-beneficial uses of plant products: Addictive Drugs That Are Actually Pesticides

Choose ONE of the following compounds:

  • Caffeine
  • Cocaine
  • Nicotine
  • Artemisinin

Answer these four questions:

  1. Describe the compound and in what plant(s) it is found. 
  2. Explain how this compound provides protection for the plant.
  3. Does the compound provide any other benefits for the plant, such as enhanced pollination?
  4. What effect does the compound have on humans?

Follow these guidelines for your paper: 

  • Utilize at least 1 credible source to support the arguments presented in the paper. Make sure you cite appropriately within your paper, and list the reference(s) in APA format on your Reference page.  
  • Your paper should be 1–2 pages in length, not counting the Title page and Reference page.

Joyce is a 34-year-old woman who has been married 10 years. She has three children, all less than 10 years old: Sheena (age 9), Jack (age 6), and Beth (age 2). Her husband is a prominent attorney. They present an ideal picture of an upper-middle-class family. They live in a fashionable suburb. The husband has been successful to the extent that he has been made a full partner in a large law firm. The family is very active in church, the country club, and various other social organizations. Joyce is an active member of several charitable, civic, and social groups. Joyce’s initial call to the abuse center was vague and guarded. She expressed an interest in inquiring for “another woman” in regard to the purpose of the center. After she had received information and an invitation to call back, a number of weeks elapsed. Joyce’s second call occurred after receiving a severe beating from her husband.

Joyce tells the crisis worker in the phone:”Well, last night he beat me worse than ever. I thought he was really going to kill me this time. It had been building up for the past few weeks. His fuse was getting shorter and shorter, both with me and the kids. It’s his work, I guess. Finally he came home late last night. Dinner was cold. We were supposed to go out, and I guess it was my fault . . . I complained about his being late, and he blew up. Started yelling that he was gonna teach me a lesson. He started hitting me with his fists . . .knocked me down . . . and then started kicking me. I got up and ran into the bathroom. The kids were yelling for him to stop and he cuffed Sheena . . . God, it was horrible! (Wracked with sobs for more than a minute. CW waits.) I’m sorry, I just can’t seem to keep control.”

As the crisis worker:

1-What typical dynamics did you see occurring—denial, guilt, fear, rationalization, withdrawal, and so on—in the victim? How would you as the crisis worker handle them?

What are some of the domestic violence intervention strategies? Pick one and how would you apply it to the scenario
