    Assignment Prompt & Instructions

    ## Overview
    In this project, you will apply inference methods for means to test your hypotheses about the housing sales market for a region of the United States. You will use appropriate sampling and statistical methods.
    ## Scenario
    You have been hired by your regional real estate company to determine if your region’s housing prices and housing square footage are significantly different from those of the national market. The regional sales director has three questions that they want to see addressed in the report:
    1. Are housing prices in your regional market lower than the national market average?
    2. Is the square footage for homes in your region different than the average square footage for homes in the national market?
    3. For your region, what is the range of values for the 95% confidence interval of square footage for homes in your market?
    You are given a real estate data set that has houses listed for every county in the United States. In addition, you have been given national statistics and graphs that show the national averages for housing prices and square footage. Your job is to analyze the data, complete the statistical analyses, and provide a report to the regional sales director. You will do so by completing the Project Two Template located in the What to Submit area below.
    ## Directions
    **Introduction**
    1. **Region:** Start by picking one region from the following list of regions:
    West South Central, West North Central, East South Central, East North Central, Mid Atlantic
    2. **Purpose:** What is the purpose of your analysis?
    3. **Sample:**Define your sample. Take a random sample of 500 house sales for your region.
    1. Describe what is included in your sample (i.e., states, region, years or months).
    4. **Questions and type of test:** For your selected sample, define two hypothesis questions (see the Scenario above) and the appropriate type of test for each. Address the following _for each hypothesis_:
    1. Describe the population parameter for the variable you are analyzing.
    2. Describe your hypothesis in your own words.
    3. Identify the hypothesis test you will use (1-Tail or 2-Tail).
    5. **Level of confidence:** Discuss how you will use estimation and confidence intervals to help you solve the problem.
    **1-Tail Test**
    1. **Hypothesis:**Define your hypothesis.
    1. Define the population parameter.
    2. Write null (Ho) and alternative (Ha) hypotheses. **Note:** For means, define a hypothesis that _is less than_ the population parameter.
    3. Specify your significance level.
    2. **Data analysis:**Summarize your sample data using appropriate graphical displays and summary statistics and confirm assumptions have not been violated to complete this hypothesis test.
    1. Provide at least one histogram of your sample data.
    2. In a table, provide summary statistics including sample size, mean, median, and standard deviation. **Note:** For quartiles 1 and 3, use the quartile function in Excel:
    =QUARTILE([data range], [quartile number])
    3. Summarize your sample data, describing the center, spread, and shape in comparison to the national information (under Supporting Materials, see the National Summary Statistics and Graphs House Listing Price by Region PDF). **Note:** For shape, think about the distribution: skewed or symmetric.
    4. Check the conditions.
    1. Determine if the normal condition has been met.
    2. Determine if there are any other conditions that you should check and whether they have been met. **Note:** Think about the central limit theorem and sampling methods.
    3. **Hypothesis test calculations:**Complete hypothesis test calculations.
    1. Calculate the hypothesis statistics.
    1. Determine the appropriate test statistic ( _t_). **Note:** This calculation is (mean – target)/standard error. In this case, the mean is your regional mean, and the target is the national mean.
    2. Calculate the probability ( _p_ value). **Note:** This calculation is done with the T.DIST function in Excel:
    =T.DIST([test statistic], [degree of freedom], True) The degree of freedom is calculated by subtracting 1 from your sample size.
    4. **Interpretation:**Interpret your hypothesis test results using the p value method to reject or not reject the null hypothesis.
    1. Relate the _p_ value and significance level.
    2. Make the correct decision (reject or fail to reject).
    3. Provide a conclusion in the context of your hypothesis.
    **2-Tail Test**
    1. **Hypotheses:**Define your hypothesis.
    1. Define the population parameter.
    2. Write null and alternative hypotheses. **Note:** For means, define a hypothesis that is _not equal to_ the population parameter.
    3. State your significance level.
    2. **Data analysis:**Summarize your sample data using appropriate graphical displays and summary statistics and confirm assumptions have not been violated to complete this hypothesis test.
    1. Provide at least one histogram of your sample data.
    2. In a table, provide summary statistics including sample size, mean, median, and standard deviation. **Note:** For quartiles 1 and 3, use the quartile function in Excel:
    =QUARTILE([data range], [quartile number])
    3. Summarize your sample data, describing the center, spread, and shape in comparison to the national information. **Note:** For shape, think about the distribution: skewed or symmetric.
    4. Check the assumptions.
    1. Determine if the normal condition has been met.
    2. Determine if there are any other conditions that should be checked on and whether they have been met. **Note:** Think about the central limit theorem and sampling methods.
    3. **Hypothesis test calculations:**Complete hypothesis test calculations.
    1. Calculate the hypothesis statistics.
    1. Determine the appropriate test statistic ( _t_). **Note:** This calculation is (mean – target)/standard error. In this case, the mean is your regional mean, and the target is the national mean.]
    2. Determine the probability (p value). **Note:** This calculation is done with the TDIST.2T function in Excel:
    =T.DIST.2T([test statistic], [degree of freedom]) The degree of freedom is calculated by subtracting 1 from your sample size.
    4. **Interpretation:** Interpret your hypothesis test results using the _p_ value method to reject or not reject the null hypothesis.
    1. Compare the _p_ value and significance level.
    2. Make the correct decision (reject or fail to reject).
    3. Provide a conclusion in the context of your hypothesis.
    5. **Comparison of the test results:**Revisit Question 3 from the Scenario section: For your region, what is the range of values for the 95% confidence interval of square footage for homes?
    1. Calculate and report the 95% confidence interval. Show or describe your method of calculation.
    **Final Conclusions**
    1. **Summarize your findings:** In one paragraph, summarize your findings in clear and concise plain language.
    2. **Discuss:** Discuss whether you were surprised by the findings. Why or why not?

    Your work on the new student committee was a huge success! The director of new student recruitment has requested that you continue your work on the committee. Specifically, the director would like you to distribute a small survey to the students who attended the weekend event, gauging their level of interest in studying at UGC. The director is interested in obtaining demographic information from the prospective students, the academic program into which they would enroll, and their overall level of interest in attending UGC. The survey questions and results are below:
    **Survey questions given to prospective students**
    – **What      is your age?**
    – **Would      you live in on-campus housing or off-campus housing?**
    – **Into      which academic program would you enroll?**
    – **How      likely are you to attend UGC in the next year? (Rate: 1–4, 1 is not likely      and 4 is very likely)**

    Your first task is to define the data resulting from each survey question as qualitative or quantitative. If the variable is qualitative, indicate if it is nominal or ordinal. If it is quantitative, indicate whether it is discrete or continuous and whether it is interval or ratio (see graphic below).
    Next, create a table (a frequency distribution, stem and leaf plot, or a grouped frequency distribution) to organize the data from one of the variables. Include the table in your post. Does including the relative frequency or cumulative frequency make the table more meaningful? Why do you feel this table best organizes the data?
    Then, consider how you might visually display the results as a graph (bar graph, Pareto chart, dot plot, line graph, histogram, pie chart, or box plot). Include the graph in your post. Why did you choose this graph? Explain why you believe this graph is the best choice to display the data.
    Finally, find the mean, median, and mode for _one_ of the variables. Which of these measures of central tendency do you think is the best choice for "average" and why? Find the range and standard deviation (measures of dispersion) for the variable. What would a narrower or wider deviation signify in the context of this data?
    Your initial post to the discussion (covering the four tasks above) is due by 21ST 11:59 p.m. EST on Saturday.
    Consider the graphs/charts and measures of central tendency and dispersion that your peers have chosen. Do they align with your choices? Discuss at least one benefit of your peers' choices. Can you share a recommendation to improve their choices?

    Probability tells us the chance or likelihood that a particular event will occur. Whether or not we realize it, every day we use probability to make decisions. For instance, when deciding whether to take an umbrella, we check the weather forecast to see the probability that it will rain. In this instance, probability tells us the likelihood that it will rain; however, the decision about taking an umbrella is based on an individual's willingness to risk getting rained on. Some people will take an umbrella when the probability of rain is at least 40%, while others will wait until the probability is at least 60%.
    What are two examples of when you have used probability to make a decision? One example should be from your personal life and one from your work life. If you do not work, show two examples from your personal life. Provide specific numeric values to show how you made the decision. Share this information in your initial post to the discussion.
