please do questions 2 and 18 from chapter 12, follow instructions, do not use AI !!!
INSTRUCTIONS BELOW USE PDF FOR CHAPTER 12 QUESTIONS
Chapter 12
Question 2. Brief answer Question 18. (ignore instructions in the book and follow the steps I describe above. Do the problem both ways, i.e., showing all the work [EXCEL or writing it out] AND using one of the software options [SPSS or Jamovi — cut and paste results]). Assume that you predict that the “text” group will have higher ratings of competence than the other two groups (i.e., you make specific predictions). Produce a chart that helps you interpret the findings and include error bars (95% confidence intervals) for groups. Be specific with respect to any group mean differences you find. Report effect size for overall F-test.
**note, effect size for ANOVA is eta-squared
Non-book questions (use the data sets provided on the blackboard to answer these questions).
1. Using the Politics data set, test whether mean levels of the personality factors openness to experience (opentot) and disagreeableness (disagreeable) differ across the political party groups (polparty: republicans, democrats, independents and not registered). Assume that this is an exploratory analysis, and you have no predictions about how the groups might differ, thus, you want greater protection against making a type 1 error. Produce charts that helps you interpret the findings and include error bars (95% confidence intervals) for groups. Be specific with respect to any group mean differences you find, i.e., tell me who is significantly higher/lower. Report effect size for overall F-test.

IHP 525 Journal Guidelines and Rubric
Overview
The journal activities in this course are an ongoing, private conversation between you and the instructor. In each journal assignment, you will draft responses to sections of Final Project Article Review. While a certain level of informality is permitted, proper grammar, spelling, and APA citations are required. Your journal posts should reflect academic rigor.
A course journal is generally made up of many individual assignments. In this course, each assignment will be graded individually, but they will all be polished and used to create one final document to be submitted in Module Eight as your Final Project Article Review.
Prompt
For each journal assignment, the following critical elements must be met:
Fulfill all requirements in the individual prompt.
Provide relevant application of course concepts.
Support ideas and observations with examples from your own personal or professional situation.
What to Submit
Submit assignment as a Word document with double spacing, 12-point Times New Roman font, and one-inch margins.

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:
Are housing prices in your regional market lower than the national market average?
Is the square footage for homes in your region different than the average square footage for homes in the national market?
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.

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?

Steps to Complete the Week 7 Lab
Step 1: Find these articles in the Chamberlain Library. Once you click each link, you will be logged into the Library and then click on “PDF Full Text”.
First Article: Confidence Intervals, https://chamberlainuniversity.idm.oclc.org/login?url=http://search.ebscohost.com/login.aspx?direct=true&db=c8h&AN=104521394&site=ehost-live&scope=site
Second Article: Confidence Intervals, https://chamberlainuniversity.idm.oclc.org/login?url=http://search.ebscohost.com/login.aspx?direct=true&db=c8h&AN=104457984&site=ehost-live&scope=site
Step 2: Consider the use of confidence intervals in health sciences with these articles as inspiration and insights.
Step 3: Using the data you collected for the Week 5 Lab(see below) (heights of 10 different people that you work with plus the 10 heights provided by your instructor), discuss your method of collection for the values that you are using in your study (systematic, convenience, cluster, stratified, simple random). What are some faults with this type of data collection? What other types of data collection could you have used, and how might this have affected your study?
Step 4: Now use the Week 6 Spreadsheet (see below)to help you with calculations for the following questions/statements.
a) Give a point estimate (mean) for the average height of all people at the place where you work. Start by putting the 20 heights you are working with into the blue Data column of the spreadsheet. What is your point estimate, and what does this mean?
b) Find a 95% confidence interval for the true mean height of all the people at your place of work. What      is the interval? [see screenshot below]
c) Give a practical interpretation of the interval you found in part b, and explain carefully what the output       means. (For example, you might say, “I am 95% confident that the true mean height of all of the              people in my company is between 64 inches and 68 inches”).
d) Post a screenshot of your work from the t value Confidence Interval for µ from the Confidence                  Interval tab on the Week 6 Excel spreadsheet
Step 5: Now, change your confidence level to 99% for the same data, and post a screenshot of this table, as well.
Step 6: Compare the margins of error from the two screenshots. Would the margin of error be larger or smaller for the 99% CI? Explain your reasoning.
