Mathematics

Its a statistics project. Please make sure you are very good in statistics to start this project. I will be attaching the full instruction in a word document to this order. This is part of the project instruction: Find a statistical study from your field of interest online or in print. This should be a journal article or other short research work, but not a collection of raw data. Explain each of the following: 1.) Explain the purpose of this study. 2.) Using what you have learned in statistics, explain the findings. This should include at least three separate analyses including but not limited to: measures of central tendencies, measures of dispersion, measures of position, confidence intervals, and/or hypothesis testing . 3.) Your writing should have a brief introduction and conclusion. Note, your introduction may include the purpose of the study. 4.) A reference page is mandatory. Properly cite any and all sources you use during this assignment.

Buying vs. Renting In this project you will create an Excel Workbook consisting of two sheets. You will then use it to perform various financial calculations and answer 10 questions. Specifically, you will be examining whether it is better to buy a home or rent, depending on things such as income, property and income taxes, appreciation, annual percentage rate, etc. In addition to your completed project, you must compose a response to the Project 3 Discussion Board prompt and respond to at least two of your classmates’ post with a substantive reply to each. Project 3 – Buying vs. Renting Objective: In this project you will create an Excel Workbook consisting of two worksheets. You will then use it to perform various financial calculations and answer the questions below. Specifically, it will be used to examine whether it is better to buy a home or rent, depending on things such as income, property and income taxes, appreciation, annual percentage rate, etc. Submission: Your final submission should be a pdf containing the answers to each question below, and the Excel Workbook you created to answer the questions. Title your answers pdf as “Project 3 Answers – (your last name)”, and title your Excel Workbook as “Project 3 Workbook – (your last name)”. Your answers to each question should be given in complete sentences. If your answer is calculated by Excel, reference the cell you got the answer from. If you calculated the answer by hand using a formula or basic arithmetic, be sure to show enough work to justify your answer. The workbook will contain two worksheets within it (details on this are given throughout the questions). Project 3 –Buying versus Renting Mortgages and Taxes: Deb and Rusty have just gotten married and wish to buy a home. They both work in Boston and have a combined income of $90,000. They found a modest starter house which they are buying for $350,000. 1.They plan to use their $40,000 is savings to cover the closing costs the bank will charge them, which are 1% of the amount they borrow from the bank. The rest of the savings will be used as a down payment. For example, if they borrow $330,000 using $20,000 for a down payment, the closing costs will be $3,300, which still leaves them some savings. Determine the largest amount they can use for a down payment and still pay the closing costs. 2.Open Excel and create a 20 year amortization schedule, giving monthly payments for the amount they borrowed at a 4.5% annual interest rate. Title this worksheet Amortization. For your answer to this question write “See Excel Workbook”. 3.Use the amortization schedule to compute the total amount of interest they will pay to the bank over the 20 years. 4.Deb and Rusty know that buying a house will save them money on taxes because they get to deduct the interest they pay to the bank each year and the property taxes they pay each year. First create a separate worksheet from the amortization schedule. Title this worksheet Analysis. In this worksheet, create a column titled Income starting at $90,000 and increasing at 3% for 20 years. What is their income after 20 years? 5.Next create the following columns in your new Excel worksheet. For your answer to this question write “See Excel Workbook”. •Property Taxes which are currently $3,100 a year and will also increase by 3% a year. •Interest paid to the bank each year (careful here, your amortization schedule is monthly). •Yearly Deduction: Do a Google search for Standard Deduction for current year/married filing jointly •Taxable Income (Taxable Income = Income –Deductions). 6.Go to www.savewealth.com click on Tax Forms, Income Tax Rates, and then Married Filing Jointly to find the tax formula for Deb and Rusty. Create a column computing the yearly Federal Income Taxes. 7.Assume the rent is now $1000 a month and will increase by 3% each year. Compute theiryearlyfederal income taxes (which are higher when renting because they don’t have the deductions). 8.By renting they are saving a lot of money each year! They pay less for rent than a mortgage, and they don’t pay property taxes (they do however pay more in income tax). Assume the extra money (include the $40,000 in savings as initial deposit) theyhave from renting versus buying is all invested at 10% a year, and every year their extra money is added to this account. Create a column titled Extra Money. How much extra money do they have after 20 years? 9.Assume the house increases in value by 3% a year. Which option ends up with more money for Deb and Rusty to retire on assuming they sell the house after 20 years? 10.Write a paragraph or two reflecting on this assignment. Were there any calculations that were surprising to you? Do you feel this analysis leaves out anything important (this could be something financial that wasn’t included, or something related to quality of life)? For instance, renting might allow for more freedom or flexibility, while buying makes some people feel more secure. Give your opinion about how the analysis might be improved, or explain what aspects of their decision are important but cannot be analyzed numerically.

Grade A sugar costs 75 sh per kg and grade B sugar costs sh 50 per kg. Angela mixed the two grades and sold the mixture at sh 72 per kg. In so doing she made a profit of 20%. In what ratio did she mix them? 

1. It is often difficult to find the exact mean (average) of a large population of data. We use confidence Intervals to estimate where we think the true mean lies. Discuss the advantages of using a confidence interval. Give an example of a large population of data that is suited to a confidence interval estimate- in other words, it would be very hard to find the exact true mean of the data. 2.

Your task for this discussion is as follows: Write a system of two linear equations that model something from your daily life. Solve the system of equations in two ways. Discuss which method you liked better and why. In your responses to peers, compare and contrast your preferences for how to solve systems of equations.

What is a series? What are some tests used to determine whether an infinite series converges or diverges? What is a power series? What are some tests used to determine whether a power series converges on a particular domain? How can power series be applied to the study of differential equations? Given a series that converges how can a finite value be assigned to it in general? What is the intuitive motivation for Ces`aro summation? Are there series that are divergent when looking at the sequence of partial sums, but yet have a finite Ces`aro sum? (Basically just answers these questions, and related with “real-analysis” in Math) The goal of this assignment is for you to pick out a topic of your choice and explore the said topic. By design all material in mathematics usually has many theorems and results that can be discussed, but the goal is to pick out some themes and enough details so as to be able to provide enough information for a formal write-up. The write-up should contain: – a title – your name, the university’s name, and the due date – an abstract – an introduction – sections (the breakup of which completely depends on the topic chosen) – properly labeled lemmas, theorems, proofs, corollaries, examples, etc… – a conclusion – references Grade Breakup: The total is 100 points. 5 Points: Title, Name, University Name, Due Date, and Confirmation of Minimum Length of 7 Pages 10 Points: Abstract 10 Points: Introduction 60 Points: Main Content in Sections 10 Points: Conclusion 5 Points: References

Description In this discussion, you will explore the zeros of polynomials. Instructions Step 1: Respond to the following: Imagine you are writing exam questions for an algebra course. You want to write questions that include finding the zeros of polynomials. To balance the difficulty level of the test’s questions, you decide to include two different types of questions, as described here: Question #1: A polynomial of degree at least 3 where all the zeros are positive whole numbers Question #2: A polynomial of degree at least 3 where one or more of the roots are fractions Find two polynomials for the two described questions. Explain how you know each question satisfies the requirements stated. What approach did you use to find these polynomials? Discussion Board 9: Vaccination and Immunity Description: Discuss the process of vaccination and how it confers immunity to the person being vaccinated. Apply this knowledge to the clinical setting to define the effectiveness and safety of vaccines. Objectives: Describe the concept of vaccination and how it produces immunity. Instructions: Step 1: Respond to the following prompts. A patient presents in your office to get their child vaccinated, and you as the healthcare provider are tasked with administering the vaccine. Before allowing their child to be vaccinated, they relay to you that they have been researching vaccination online and have concerns with regards to vaccine effectiveness and safety. What would be your response to this concerned parent? How would you support the safety and effectiveness of vaccines using statistically significant evidence? Step 2: Read other students’ posts and respond to at least two other students. Incorporate personal experience, if appropriate, to help support or debate other students’ posts. If differences of opinion occur, debate the issues and provide examples to support opinions. Be sure to cite any outside sources in current APA format. Discussion Board 9: Public Speaking Description: In this discussion, you will explore the advantages and disadvantages of self-disclosing apprehension with members of an audience. Objectives: Explore the nature of public speaking and suggestions for managing anxiety and procrastination. Identify suggestions for managing apprehension in public speaking and for overcoming procrastination. Instructions: Step 1: Respond to the following prompts: This is your first experience with public speaking and you’re very nervous. You’re afraid you’ll forget your speech and stumble. So you’re wondering if it would be a good idea to alert your audience to your nervousness. If you decide to say something, what are some things you might say? Are there advantages and disadvantages to what you might say? What would you say? What good reasons can you give to say nothing?

The most commonly used descriptive statistics are measures of central tendency including mean, median, and mode.

Using the information in the master budget and cash budget attached how can this be used by the managers of garden furnishing ltd to improve the financial performance and the situation of the organisation. Please consider the following issues that have arose within the organisation Revenues and selling prices are on a similar level to competitors but business has much higher costs than competitors do, which seems to be leading to smaller profit margins than its direct competitors are. The business is also very seasonal (high sales in spring and summer) therefore; the lack of budgeting has regularly left the business in very bad cash flow situations. Garden Furnishings Ltd is a manufacturing business that produces garden furniture for the retail market. It is a family owned business that has historically had a relaxed approach to budgeting and business in general with a reluctance to change. The business is seasonal and although selling prices are comparable to those of their competitors, the profit margins are low. Individual managers are unaware of their expectations and use prior experience to base decisions on purchasing and production levels rather than a planned and co-ordinated multi-level approach. Procedures are not standardised and there is no recognition for managers that limit waste production compared to those that do not.

Statistics is about more than calculations. It is about turning data into information and using this information to understand the population. A statistician will be asked to help solve real-world problems by designing a study, collecting data, analyzing the data, and writing up the results. As a final project, you will be asked to do something similar. Though the design and data collection will be done for you, you will be asked to analyze the data using the appropriate tests (ensuring the data are distributed normally) and write up the results, using statistical evidence to support your findings. Lastly, you will be asked to include recommendations, that is, apply the results to solve the real world problem. In your paper, explain why you chose each statistical test, figure, or procedure Due to financial hardship, the Nyke Shoe Company feels they only need to make one size of shoes, regardless of gender or height. They have collected data on gender, shoe size, and height and have asked you to tell them if they can change their business model to include only one size of shoes—regardless of height or gender of the wearer. In no more than 5–10 pages (including figures), explain your recommendations, using statistical evidence to support your findings. The data found are given in the following table. Only use results in the paper. You may show your work in an appendix, if you would like
