SNHU Selling Price and Area Analysis for Real Estate Company Project
ScenarioSmart businesses in all industries use data to provide an intuitive analysis of how they can get a competitive advantage. The real estate industry heavily uses linear regression to estimate home prices, as cost of housing is currently the largest expense for most families. Additionally, in order to help new homeowners and home sellers with important decisions, real estate professionals need to go beyond showing property inventory. They need to be well versed in the relationship between price, square footage, build year, location, and so many other factors that can help predict the business environment and provide the best advice to their clients.PromptYou have been recently hired as a junior analyst by D.M. Pan Real Estate Company. The sales team has tasked you with preparing a report that examines the relationship between the selling price of properties and their size in square feet. You have been provided with a Real Estate County Data document that includes properties sold nationwide in recent years. The team has asked you to select a region, complete an initial analysis, and provide the report to the team.Note: In the report you prepare for the sales team, the response variable (y) should be the median listing price and the predictor variable (x) should be the median square feet.Specifically you must address the following rubric criteria, using the Module Two Assignment Template:Generate a Representative Sample of the Data
Select a region and generate a simple random sample of 30 from the data.Report the mean, median, and standard deviation of the median listing price and the median square foot variables.Analyze Your SampleDiscuss how the regional sample created is reflective of the national market.
Compare and contrast your sample with the population using the National Statistics and Graphs document.Explain how you have made sure that the sample is random.Explain your methods to get a truly random sample.Generate ScatterplotCreate a scatterplot of the x and y variables noted above and include a trend line.Observe patternsAnswer the following questions based on the scatterplot:Define x and y. Which variable is useful for making predictions?Is there an association between x and y? Describe the association you see in the scatter plot.What do you see as the shape (linear or nonlinear)?If you had a 1,200 square foot house, based on the regression equation in the graph, what price would you choose to list at?Do you see any potential outliers in the scatterplot?
Why do you think the outliers appeared in the scatterplot you generated?What do they represent?

CU Educational Attainment Differences in First & Second Gen Hispanics & Asians Discussion
In this chapter, we examined the difference in educational attainment between first- and second-generation Hispanic Americans and Asian Americans based on the proportion of each group with a bachelor’s degree. We present additional data from the Pew Research Center’s 2013 report, measuring the percentage of each group that owns a home (Frankfort-Nachmias, & Leon-Guerrero, 2018, p. 231).First-Generation Hispanic Americans (N = 899), 43% own a homeSecond-Generation Hispanic Americans (N = 351), 50% own a homeFirst-Generation Asian Americans (N = 2,684), 58% own a homeSecond-Generation Asian Americans (N = 566), 51% own a homeSource: Pew Research Center, Second-Generation Americans: A Portrait of the Adult Children of Immigrants.

Is there a significant difference between first-and second-generation Hispanic American populations?
Yes
No
Question 2 3 Points What is the difference? -2.33 2.33 0.0198 0.07 Question 3 2 Points Is there a significant difference between first-and second-generation Asian populations?
Yes
No
Question 4 2 Points What is the difference? 3.50 -3.50 0.0004 0.07
In 2016, the Pew Research Center surveyed 1,799 white and 1,001 black Americans about their views on race and inequality. Pew researchers found “profound differences between black and white adults in their views on racial discrimination, barriers to black progress and the prospects for change.” White and black respondents also disagreed about the best methods to achieve racial equality. For example, 34% of whites and 41% of blacks said that “bringing people of different racial backgrounds together to talk about race” would be a very effective tactic for groups striving to help blacks achieve equality.Test whether the proportion of white respondents who support this tactic is significantly less than the proportion of black respondents.
Question 5 2 Points What is the null hypotheses? π₁ ≠ π₂ π₁ = π₂ μ1 = μ2 μ1 ≠ μ2 Question 6 2 Points What is the research hypotheses?
π₁ ≠ π₂
π₁ = π₂

Question 8 2 Points What is your decision (step 5 in hypothesis testing)? Do you accept or reject the null hypothesis? Accept Reject
We compare the proportion who indicated that it was “very important” to be born in this country to be American for two GSS 2014 groups: respondents (1) born in the United States (native born) and (2) not born in the United States (foreign born). Test the research hypothesis that a higher proportion of native-born respondents than foreign-born respondents indicated being born in the United States was “very important” to be American. Set alpha at 0.05.
Question 9 2 Points Do you accept or reject the null hypothesis? Accept Reject
