One page response. No Plagiarism. Due in 8 hours. Attached the Turnintin ReportPart 1: Interpreting CorrelationsA meta-analysis (Anderson & Bushman, 2001) reported that the average correlation between time spent playing video games (X) and engaging in aggressive behavior (Y) in a set of 21 well-controlled experimental studies was r+ = .19. This correlation was judged to be statistically significant. In your own words, what can you say about the nature of the relationship? Write a one-page response to this question.

An interesting resource for journalists from Harvard University’s Kennedy School can be found here. Please take a look at this explanation. Then choose a study from the site’s menus (Government, Economics , etc.) or the search menu.  Please choose a study that includes regression analysis and briefly present a study to the class.  Define Y, X (or X’s) and some key findings, for example thinking about the characteristics of estimated coefficients you discussed last week.  Include the link for the study in case.(Note: this is the kind of applied regression analysis I mentioned in an earlier video in which there is little/no discussion of the error terms.)link: https://journalistsresource.org/tip-sheets/research/regression-analysis-primer-for-journalists/

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.

Just tell me we will use two Sample independent tests or the two-sample dependent test and why. An experiment was carried out to compare recall ability when reading electronically compared to hard copy. Thirty students from a first-year university English class agreed to participate. Each student was shown a randomly generated list of 40 five-letter words on a tablet and given 2 minutes to memorize them. They were then given 4 minutes to write down as many of the words as they could recall. An hour later, the students repeated the experiment but this time the list of 40 five-letter words was given to them on a piece of pape

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.

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.

This is a test of problem-solving skills. It contains 50 questions that must be answered without using a calculator, dictionary, or other resources. You will have exactly 12 minutes to provide as many correct answers as you can. Many people do not finish all of the questions, but do your best. Guessing is not likely to improve your score. However, if you think you know the answer, but are not sure, then mark your best choice and move on. Do not skip around or spend too much time on any one question. Be sure to have two pencils and a piece of scratch paper before you begin.

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
