Running head: THE IMPORTANCE OF RELATIONSHIPS The Importance of Relationships – Confidence Interval Name Institution Date 1 THE IMPORTANCE OF RELATIONSHIPS 2 A confidence interval provides a better understanding of the range within which the actual value lies. The accuracy of a confidence of interval depends on the margin of error which is being developed within a given study focus. The margin of error incorporates the level of significance that represents the error or the degree of variation, which the confidence interval upper and lower values will be bounded. The degree of variation can be 10%, 5% or 1% depending on the level of accuracy that a researcher wishes to have the research. A 99 % confidence level shows a high degree of accuracy considering a 1% error. The 90% confidence level has a very high degree of variation and a low accuracy considering the 10% error that is in ...

Let’s consider the US national debt and the US population as a function of time.1. The current population of the United States is 317,000,000.The current national debt total is $17,000,000,000.Based on these figures, use algebraic equations to calculate the approximate amount ofdebt per citizen. Show all of your work.2. For the purposes of this project, assume that population growth is a linear function thatgrows at a steady, unchanging rate of 0.9% per year, and that debt growth is a linearfunction that grows at a steady, unchanging rate of 13% per year.Use the population and debt figures from #1. Show all of your work.Find the linear equation for population in slope-intercept form.Find the linear equation for debt in slope-intercept form.3. Graph the linear equation for population growth and debt in separate graphs. Label thevalues of the x- and y-axes and title the graph. Show x from 0 (current year) to 30 (30years from now). Determine what the population and national debt will be 30 years fromnow. Calculate what the debt per citizen will be in 30 years. Show all your work. 4. Using calculations from #1 and # 3, calculate the population, national debt, and debt percitizen in 10 and 20 years from now. Complete the table below with your calculations: Time (years) Debt ($) Population Debt/Citizen0 17,000,000,000 317,000,000102030Graph the function that shows the amount of debt per citizen as a function of time. Labelthe values of the x- and y-axes and title the graph. Show x from 0 (current year) to 30(30 years from now). Identify the ordered pairs at x = 0, 10, 20 and 30 years either onthe graph or below it. Is this a linear function? Why or why not? 5. If the current compound interest rate on our national debt is 8% (compounded annually),what will the national debt be in 5, 10, and 20 years? The current national debt is$17,000,000,000. Show equations for all three calculations. Please find the exact values,do not round.6. At what point does the compound interest on the national debt double the amount fromthe current year? The current national debt is $17,000,000,000. Solve algebraically, andshow all of your work. Find the exact value. Assume the interest rate is 8% and theinterest rate is compounded annually.

MA141 Grantham Week 7 Precalculus: Application Assignment Assignment

Week Seven – Application AssignmentAnswer the following questions in a Word document and upload the document to the appropriate drop box.1) A straight road rises at an inclination of 0.3 radian from the horizontal. Find the slope and change in elevation over a one-mile section of the road.2) In order to allow rain to run off of a road, they are often designed with parabolic surfaces in mind. Suppose a road is 32 feet wide and 0.4 foot higher in the center than it is on the sidea) Write an equation of the parabola with its vertex at the origin that models the road surface.b) How far from the center of the road is the road surface 0.2 feet lower than the center?3. A parabolic archway is 12 meters high at the vertex. At a height of 10 meters, the width of the archway is 8 meters. How wide is the archway at ground level?4) Halley’s comet follows an elliptical orbit with the sun as one of the foci. The eccentricity of the orbit is approximately 0.967. The length of the major axis of the orbit is approximately 35.88 astronomical units. (An astronomical unit is about 93 million miles.(a) Find an equation of the orbit. Let the origin represent the sun and use the x axis as the major axis.(b) Find the greatest and least distances (the aphelion and perihelion, respectively) from the sun’s center to the comet’s center.5) You and a friend live 4 miles apart. You hear the sound of thunder 18 seconds before your friend hears it. Assuming sound travels at 1100 feet per second, determine where the lightning occur?

In this unit, you need to submit the rough draft, as far as you have gotten, for feedback and improvement, for your final draft.In Unit 2, you did the below: --As preparation for the final research paper, you formulated a theory about the correlation between measurable independent variables (causes) and one measurable dependent variable (the effect). Be sure to have at least two independent variables for proposed research paper. This rough draft should include the following four items which serve as the foundation for the final research paper after instructor feedback is given.Unit 5: 20 points (These steps total to 20 points).Create a draft of your report including the data. This copy of the data may be in an Excel spreadsheet. **Below is a copy of the requirements for your proposal from Unit 2.1) Purpose Statement [20%]In one paragraph, state the correlation and identify the primary independent variables.State the correlation as in the following:“The dependent variable _______ is determined by independent variables ________, _________, ________, and ________.”Identify and defend the “primary” independent variable, or the variable believed to have the strongest impact on the dependent variable:“The most important independent variable in this relationship is ________ because _________.”2) Definition of Variables [20%]For each variable, write a single definition paragraph talking about the variable. Paragraphs should be in this order: dependent variable, primary independent variable, and three independent variables.In addition to defining the independent variables, defend why each determines the dependent variable.For the primary independent variable, at least two research sources that discuss the variable also must be cited. These sources need not be technical documents but should contain evidence to justify the relationship between the primary independent variable and the dependent variable. List these sources in the Works Cited (reference) page.**Note: Citations from encyclopedias, Wikipedia, blogs, abstracts, or non-governmental websites are not acceptable research sources.3) Data Description [20%]For each of the variables, at least 30 observations of cross-sectional data must be obtained. Thus for the final research paper, a data matrix that is at least 30 rows by numbers of variables must be presented.In one paragraph, identify the data sources and describe the data (i.e., which government agencies supply the data, which methods are used to compile them, when they were collected, etc.).4) Works Cited Page [20%]The final page of the proposal should be a Works Cited page listing the two research sources for the primary independent variable and the data sources, with a separate citation for each table of data, including specific table numbers for each of the sources.5) Data [20%]Submit this Word File in this Canvas section for your Term Project Rough Draft, with Data.
