Question Gulf Real Estate Properties, Inc., is a real estate firm located in southwest Florida. The company, which advertises itself as “expert in the real estate market,” monitors condominium sales by collecting data on location, list price, sale price, and number of days it takes to sell each unit. Each condominium is classified as Gulf View if it is located directly on the Gulf of Mexico or No Gulf View if it is located on the bay or a golf course, near but not on the Gulf. Sample data from the Multiple Listing Service in Naples, Florida, provided recent sales data for 40 Gulf View condominiums and 18 No Gulf View condominiums. Prices are in thousands of dollars. 1. Introduction: Describe the motivation for this research. In other words, why would it be important to analyze this topic of research? 2. Develop an appropriate graph that summarizes the data set and discuss any insights the graph reveals about the data. You may want to report more that one graph to fully describe the data set Perform the following calculations: 3. Use appropriate descriptive statistics to summarize condominium sales (For both Gulf View and No Gulf View). 4. Assume the branch manager requested estimates of the mean selling price of Gulf View condominiums with a margin of error of $35,000 and the mean selling price of No Gulf View condominiums with a margin of error of$10,000. Using 95% confidence, how large should both the sample sizes be? (Assume 𝜎 = 190,000 for gulf view and 𝜎 = 45,000 for no gulf view) 5. Develop a 99% confidence interval estimate of the population mean sales price and population mean number of days to sell for No Gulf View condominiums. Interpret your results. Provide a managerial interpretation of the interval estimate. 6. Develop a 90% confidence interval estimate of the population mean sales price and population mean number of days to sell for Gulf View condominiums. Provide a managerial interpretation of the interval estimate. 7. Summarize your results (from part 3.) and make appropriate suggestions and/or discuss any shortcomings of this research.
