You have been hired by the D. M. Pan National Real Estate Company to develop a model to predict median housing prices for homes sold in 2019. The CEO of D. M. Pan wants to use this information to help their real estate agents better determine the use of square footage as a benchmark for listing prices on homes. Your task is to provide a report predicting the median housing prices based square footage. To complete this task, use the provided real estate data set for all U.S. home sales as well as national descriptive statistics and graphs provided.DirectionsUsing the Project One Template located in the What to Submit section, generate a report including your tables and graphs to determine if the square footage of a house is a good indicator for what the listing price should be. Reference the National Statistics and Graphs document for national comparisons and the Real Estate County Data spreadsheet (both found in the Supporting Materials section) for your statistical analysis.Describe the report: Give a brief description of the purpose of your report.Define the question your report is trying to answerExplain when using linear regression is most appropriate.When using linear regression, what would you expect the scatterplot to look like?Explain the difference between response and predictor variables in a linear regression to justify the selection of variables.Data Collection

Think first of a network of roads for GPS mapping. Every road whether in a neighborhood or spanning states is included in possible paths. A dirt road is included in the overall network just like a major highway. Clearly, it is impossible to consider every possible path in every GPS mapping decision. If traveling from your house to the nearest grocery store, it is absurd to consider paths that go through another city 800 miles away. If driving from the Empire State building in New York City to the Golden Gate Bridge in San Francisco, a dirt road in Iowa might be close to on the way but doesnt need to be considered as a path.The Internet is similar to that mesh of roads with connections ranging from local cable lines to submarine optical cables traversing thousands of kilometers. Just like with the roads, not all possible paths in the network need to be considered for every packet route.Consider methods to narrow down these paths for GPS mapping or mesh network routing. What strategies and processes might be applied to have a computer algorithmically do what a person glancing at a map does naturally?For this Discussion:Choose either the GPS map routing or the Internet routing. Describe an algorithm for quickly determining the best path to take within such a broad mesh. Provide an example to show how the algorithmic process would determine a specific route for an automobile or data packet.

Your population is thriving on your island. The data you have collected now needs to be displayed and further analyzed. Use the charts you created in the probability portion in weeks 1-3 for this part of the project. Always show your calculations or explain how you used technology. Take a picture of your calculator if you used that or submit your excel worksheet.1. a. Create a Scatter Plot using the total population for each of the years from the Probability Island. The horizontal axis should always represent time.b. Use linear regression or a trendline in Excel to find the equation of the best fit line.c. Find the Correlation Coefficient. Explain what this means for your data.d. Use the equation to predict the population in year 20.2. a. Use the first and last data points of the total population for each of the years from the Probability Island to find a linear equation to model the data.b. Graph the equation.c. Compare the slope of the Linear Regression Line of question 1 with the slope of this line. Provide an explanation of why they may similar or differ.d. Use the equation to predict the population in year 20.3. a. Assume that (0,150) represents the vertex of a quadratic equation. Find a quadratic equation using the tenth-year population as another point.b. Graph the equation.c. Use the equation to predict the population in year 20.4. Using the equation y = 2×2 -9x +4, explain and demonstrate how to find the x-intercepts, the y-intercept, the axis of symmetry, and the vertex of a quadratic equation.

Payday LoansPayday loans are high-interest short-term loans, usually over a period of two weeks. One recurring political question is whether or not interest rates on such loans should be capped. Roughly speaking, those in favor of caps want to protect consumers from potentially harmful loans, while those against caps want to let the free market determine what the rate should be.1.) Watch the video and read the article below.Oliver, J. (2014). Predatory lending: Last week tonight with John Oliver.
