Project 2. Testing a Claim about A Population Mean:
One-Sample T-Test
[Read through this entire assignment before you start.]
The purpose of the project is for you to gain experience in applying the methods you have learned in Chapters 7 and 8 to
real data of interest.
The goal of the analysis is to understand the mean (median) price for housing in a given region (Part A) with a random
sample drawn from a select zip codes (Part B) within the region or city. Note, we have to use the median since that is
the way the census measures housing prices.
Your group will need to choose a region and you individually will need to choose a zip code within that region to
conduct a one-sample hypothesis t-test. Details of the assignment, grading, and due dates are below.
Grading
Project 2 is worth 10% of your total grade. There are two parts to the project. Part A is a group collaboration with
required Zoom presentation and Part B is your own data analysis. Part A is worth 20 points and Part B is worth 80
points. You may choose to only do Part B and not do Part A; however, this will allow you to only receive 80 out of 100
points (or 80%).
Important Dates and Participation Requirement
1. Project Proposal Due by 5/6/24 (4 POINTS). Everyone needs to complete the Project 2 Proposal in Canvas
individually to receive credit. Individuals with late submission will receive score of 0 and points will be deducted
from Part B of the assignment. You will need information from STEPS 1-5 below to complete the Final
Project Proposal in Canvas.
2. Part A. Group Project Presentation. Upload PDF of one copy of Group Presentation slides to Canvas by
5/9/24. Group virtual presentation is on Friday 5/10/24. Sign-up for a 15 minute slot in Google here
Links to an external site.. One slot per group and you must be in groups of 3 or 4. Individual presentations are not
accepted and will not be given credit. The entire group presentation is to be no more than 10 minutes. If none of
the time slots work for your group, contact the instructor ASAP.
During the presentation, everyone in your group must present at least the slides for their own zip code
(details in STEP 5 below).
Any group member who fails to show-up or present during the presentation will receive a 0 for Part A of
this assignment.
3. Part B. Individual Project Analysis Submission. 5/13/24 (80 POINTS). .
Steps to Complete Part A — Group Collaboration (20 POINTS):
The goal of Part A is to collaborate on understanding median price of a house in a region, a group presentation, and help
your peers who are having trouble in the class. Everyone is responsible for their own analysis. You should not be doing
the work for your peers and the group will not be penalized for non-responsive group members.
STEP 1. Form a team of 3-4 people. You may join the Project 2 Discussion and Help to find groups. You should form
your groups as soon as possible. Each person will need to enter your group member names into the Project 2 Proposal,
along with information from STEPS 2 to 5.
STEP 2. Groups should sign-up for a Zoom presentation date in Google sheet hereLinks to an external site..

Project 2. Testing a Claim about A Population Mean: One-Sample T-Test: Psychology CC 5 Sec ON3 (32522) Spring 2024
STEP 3. Group should choose a city or region to explore median house price. Enter this information in the Project 2
Proposal.
STEP 4. Determine what zip codes each group member will be analyzing. Enter this information in the Project 2
Proposal.
STEP 5. Each member will use the zip codes they selected and complete Part B of the assignment. Only one analysis
will be graded regardless of the number of analysis included by an individual student.
STEP 6. Come together as a group and share your data with each other. What can you conclude about the mean
(median) housing price for your region or city?
STEP 7. Summarize your analysis and conclusion in a final group presentation in PowerPoint or Google slides (Group
to submit one version in Canvas by 5/9/24). Download the template hereLinks to an external site..
1. Team member names and project title (1 slide)
2. Research question (1 slide)
3. Briefly describe methodology (1 slide)
4. Individual analyses (Max of 1 slide per each person’s research question). Put your name on the slides
A. State your specific analysis question
B. State your claim
C. State your null and alternative hypothesis
D. State your t-statistic and p-value
E. State a conclusion about your analysis based on your result and context.
5. Group conclusion Slide. A cohesive conclusion for your group’s topic and overarching research
question. (1 slide).
STEP 9. Remember to show up to the Group Presentation! You will need to present your analysis or 50% of
group portion will be deducted. No shows will receive 0 for Part A.
Part B — Individual Data Analysis (80 POINTS):
STEP 1. Determine a zip code from which to conduct the analysis of median housing price. If you are part of a group
(Part A), make sure your zip code is unique from your group members and is within the region or city being examined
by your group.
STEP 2. Complete Project 2 Proposal. You will need to indicate your zip code. Points will be deducted from total if
Group Project 2 Proposal is not submitted.
STEP 3. Find the median price for housing in your zip code by:
I. Type the following in a Google search: “median house price in [insert your zip code]”.
II. A link to Zillow.com or Redfin should appear as the first link. Use this median price as the population price in
your hypothesis test.
This is an example:

STEP 4. Obtain your sample data.
I. Go to Zillow.com and enter the zip code for this project. In the drop down option, select “SOLD”. When you
zoom in, you will see estimated price for all houses.
II. Randomly select at least 30 houses and their estimated housing price listed on the map. Keep your sample as you
will need to enter this the in the assignment.
III. Take screenshot of the map that displays your zip code area and the prices. You will need to upload the screenshot
in your submission. After this step, you are ready to conduct your hypothesis test. Here’s an example:

STEP 5. Determine the claim you want to test about your zip code. Customized the template for your hypothesis: There
is significant [changed, increased, or decreased] in median housing price for zip code [your zip code].
STEP 6. Conduct your hypothesis test using a statistical tool such as statskingdom.com or www.geogebra.org/classic.
Keep your 30 raw data points as you will need to upload this in the assignment. Do all the following steps:
0. Check your data, 1. State the hypothesis, 2. State your significance level, 3. Calculate your test statistics, and 4. Make
a decision
STEP 7. Enter your raw data, STEP 6 results, and a screenshot of Zillow prices) in Project 2. Part B. Reporting Results,
