A university wants to determine if students from different majors are equally likely to be cited for academic dishonesty. They average instances of documented cheating across 10 years for three different academic majors and find the following results: Business Administration (M = 5.1; N = 10), Fine Art (M = 1.9; N = 10), and Nursing (M = 3.2; N = 10). They also calculated the between-group and within-group sum of squares (SS_B = 301.6; SS_W =1343.8). Use a one-way ANOVA (where α = .01) to determine if there are significant differences in cheating rates by major.

1. Identify the alternative hypothesis (F tests are always nondirectional)
2. List your degrees of freedom (within)
3. List your degrees of freedom (between)
4. List your mean squares between groups
5. List your mean squares within groups
6. List your F test statistic
7. List your critical F value(s)
8. Are there statistically significant differences in cheating between majors? (Yes/No)
9. Calculate partial eta-squared (η²) for the effect of major on cheating rates (list as decimal, 0.xx)
10. Calculate Tukey’s HSD
11. Use Tukey’s HSD to determine if the difference in cheating rates between Business Administration majors and Fine Art    majors is statistically significant (Yes/No)

1- Most real estate offers are conditional on the buyer obtaining the necessary financing to complete the purchase. Based on past​ experience, one of​Canada's largest real estate agencies believes that​ 4% of the sales fail because the buyer is unable to obtain the financing approval from their mortgage broker or lender. The real estate agency has recently submitted 60 different​ offers, all of which are conditional on financing.

What is the sampling distribution model of the proportion of clients in this group who may not receive the necessary funding to purchase the​ house? Round to one decimal.

A. Mean​ = 4.0%; standard deviation​ = 0.3%

B. Mean​ = 4.0%; standard deviation​ = 2.5%

C. Mean​ = 96.0%; standard deviation​ = 2.5%

D. Mean​ = 96.0%; standard deviation​ = 0.3%

2- The director of admission of a large university is interested in determining the proportion of students who would like to live on campus in the coming academic year.

The finance director at Ubuntu University of Science and Technology is concerned about the overhead costs at her university. Cost pressures are severe and so controlling and reducing overheads is very important. The director believes overhead costs incurred are generally a function of the number of different academic programmes, and the number of enrolled students. The following data has since been collected for analysis:

Required

a) Using the above data, estimate the regression line

. b) Calculate the coefficient of determination.

c) What insights do the analyses provide about controlling and reducing overhead costs at the university?

You are the director of admission office. Your job every year is to decide the number of offer letters to issue to undergraduate degree applicants. For the academic year 2016/2017, the school has a capacity to enroll 7,200 undergraduate students, but the school is so popular that you received more than 20,000 applications. However, you know from past year records many students not only got offer from UBC but also from other good schools in Canada and the US. The yield rate for the school is far less than 100% (the ‘yield rate’ refers to the proportion of students accept the school offers among all the students to whom UBC issue the offer letters). Assume the school has spent large amount of sunk cost in its undergraduate program for a designed capacity to enroll 7,200 students, such as upgrading classrooms, expanding residential houses, hiring additional teaching instructors and administration staff. (a) Will you issue more than 7,200 offer letters for 2016/2017 academic year? (b) What is the trade-off between issuing more than 7,200 offer letters and issuing exactly 7,200 offer letters?(c) How to determine the optimal number of offer letters to issue? What information do you need, and how to get such information?

Jak University is a leading higher education institution that is well known throughout Malaysia for its academic achievements. It is proven that this university exists in all major cities in Malaysia. Jak University is also in Kuala Lumpur and as a management center, has 100 thousand students and 10 thousand lecturers spread across several branch campuses. The learning process is done face-to-face and online. Each campus in each city can join virtual classes, so that the data from each campus can be connected to one another. Academic data from each campus branch is stored in files and then sent to the Center in Kuala Lumpur and each campus can also share data (share files). However, after this university has been operating for several years, the number of lecture transactions has increased, so that the volume of data stored in files is getting bigger. So in day-to-day operations often experience problems access to data, both when sending data and when accessing data from other campuses.

Question:

1. The University of Jak uses a file-based approach in managing its academic data. But over time began to experience problems with data accessibility.
You were appointed as a Database Consultant to change the data management process at the University of Jak using a database approach. You need to explain to the Management in Kuala Lumpur so that the leaders can understand and be sure about the proposed application of the database approach, where this approach can support operational performance in data management. Explain what is meant by a file-base approach and a database approach. Also describe the advantages and disadvantages of each.

2. If the management approves the proposal, then you need to design a good database architecture. You can choose a Three-Tier Client-Server architecture.

3. The hardware running the DBMS must continue to operate even if one of the hardware components is damaged due to various factors. One solution is to implement RAID technology. Describe what RAID technology is. Also explain by providing examples of how each RAID level is implemented.

I need to write an essay on: cause and effect/ USA spends about 54% of its total federal budget on the Military. Military spending in the USA is far greater than any nation in the world. (USA spends more on military than the next 10 highest spenders combined, 4 times China who is second on the list etc) Why does USA need to spend so much more on its military than other countries (cause), and what is/are the results of all this spending (effect)?

Create an essay which supports some position on an issue related to the following 3 topics and support by showing causes and effects. Although there are many possible strategies, most students will find it easier to focus a thesis statement a limited number of causes and effects or even on a single most important example. This will allow the essay to develop a sufficient depth. The essays should not be a simple list of causes or effects, but an essay that takes a position on why a condition exists and or argues the results of this condition. Some writers may even be able to create a strong focused thesis by suggesting a solution or arguing for some clear change of policy. The goal is to create an essay that allows you to develop a position or argument in a cause and effect essay. A strong thesis statement is very important and students should underline it in the final draft of their essay.

This essay will require research and a good deal of time learning about your chosen topic, so make sure to plan ahead and give yourself enough time to learn before you start writing.

Essay should be 4 pages long and it must have a minimum of 3 academic sources—no Wikipedia, encyclopedias, dictionaries etc. Use the library resources to find legitimate, academic sources. The Riverland Library and the library’s web site offer many useful databases and resources for researchers. Most of these sources are consider academic good, sources. I suggest you get comfortable with library and its research tools because you will need to use effective source material for our last two essays.

Western State University (WSU) is preparing its master budget for the upcoming academic year. Currently, 16,500 students are enrolled on campus; however, the admissions office is forecasting a 8 percent growth in the student body despite a tuition hike to $85 per credit hour. The following additional information has been gathered from an examination of university records and conversations with university officials:

• WSU is planning to award 200 tuition-free scholarships.
• The average class has 20 students, and the typical student takes 15 credit hours each semester. Each class is three credit hours.
• WSU’s faculty members are evaluated on the basis of teaching, research, and university and community service. Each faculty member teaches five classes during the academic year.

1.Prepare a tuition revenue budget for the upcoming academic year.

2.Determine the number of faculty members needed to cover classes.

3. Assume there is a shortage of full-time faculty members. Select at least five actions that WSU might take to accommodate the growing student body by selecting an "X" next to the action.

4.You have been requested by the university’s administrative vice president (AVP) to construct budgets for other areas of operation (e.g., the library, grounds, dormitories, and maintenance). The AVP noted: “The most important resource of the university is its faculty. Now that you know the number of faculty needed, you can prepare the other budgets. Faculty members are indeed the key driver—without them we don’t operate.” Are faculty members a key driver in preparing budgets? Yes or No?
