    ## 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?

    Homework 5

    Due Wednesday, April 9

    1. Consider the spambase data set, where emails are classi�ed as spam or not,
    and 57 feature variables are measured on each of them (see full description on
    p. 259 of the book).

    (a) Split the data set into training and test sets (roughly a 70/30 split). Com-
    pute a logistic classi�er using the training data. (There might be perfect
    separation between the groups, but that should not matter as long as you
    don�t get NA coe¢ cients.)

    (b) Find the misclassi�cation table for the test data and compute the mis-
    classi�cation rate.

    2. Consider the pendigits data set, which are samples of handwritten digits 0; 1; : : : ; 9.
    The feature variables in this case are the (x; y) coordinates of the pen tip, dis-
    cretized at eight time points (see section 7.2.1 of the book for more details).

    (a) Split the data set into training and test sets (roughly a 70/30 split). Com-
    pute the multinomial logistic classi�er using the training data.

    (b) Construct the misclassi�cation table for the test data and compute the
    misclassi�cation rate. Which digit seems to be the hardest to classify
    correctly?

    The feature variables in this case are the (x; y) coordinates of the pen tip, dis-
    cretized at eight time points (see section 7.2.1 of the book for more details).

    (a) Split the data set into training and test sets (roughly a 70/30 split). Com-
    pute the multinomial logistic classi�er using the training data.

    (b) Construct the misclassi�cation table for the test data and compute the
    misclassi�cation rate. Which digit seems to be the hardest to classify
    correctly?

  • [Solved] can you write a data table for this data and complete it?
