– Course Project- Phase 2

This week you will begin working on Phase 2 of your course project. Using the same data set and variables for your selected topic, add the following information to your analysis:

Discuss the importance of constructing confidence intervals for the population mean.
What are confidence intervals?
What is a point estimate?
What is the best point estimate for the population mean? Explain.
Why do we need confidence intervals?
Find the best point estimate of the population mean.
Construct two confidence intervals for the population mean: a 95% confidence interval and a 99% confidence interval. Assume that your data is normally distributed and the population standard deviation is unknown.
Please show your work for the construction of these confidence intervals and be sure to format your equations to fit the appropriate form (may need editing here).
Write a paragraph that correctly interprets the confidence intervals in context of your selected topic.
Compare and contrast your findings for the 95% and 99% confidence intervals.
Did you notice any changes in your interval estimate? Explain.
What conclusion(s) can be drawn about your interval estimates when the confidence level is increased? Explain.2

Introduction/Thesis
The introduction is inviting. It grabs the reader’s attention and compels him/her to read further. Engaging lead/hook.
13points
The introduction clearly states the main topic and previews the structure of the paper, but is not particularly inviting to the reader.
10points
The introduction states the main topic, but does not adequately preview the structure of the paper nor is it particularly inviting to the reader.
8points
There is no clear introduction of the main topic or structure of the paper.
5points
Not Present
0points
Content/Body Paragaphs/Evidence
There is one clear, well-focused conflict/problem to be resolved. Author uses dialogue, action, and descriiption to show not tell the story.
12points
Main idea is clear but the supporting information is general. More detail needed to “show not tell” the story.
10points
Main idea is somewhat clear but there is a need for more supporting information. Author mostly tells the story instead of showing it.
8points
The main idea is not clear. There is a seemingly random collection of information.
5points
Not Present
0points
Grammar/Punctuation/APA Style
Writer makes no errors in grammar or punctuation, so the paper is exceptionally easy to read. Follows APA style.
12points
Writer makes 1 or 2 errors in grammar or punctuation, but the paper is still easy to read. Missing one or two elements of APA style
10points
Writer makes a few errors in grammar and/or punctuation that catch the reader’s attention and interrupt the flow. Missing most APA formatting.

Hi Writer, For this assignment, We are doing an evaluation project.

Hi Writer,

For this assignment, We are doing an evaluation project. The goal is to acquire the paper’s data, and re-analyze the authors’ results with a significant portion of improvements in methods and substance, or make empirically supported criticism of the original findings.

The paper that has been assigned is by Binbin Li , I will upload it for you.

**** For this assignment, I need to write the connections with other research.

I need you to find two meta-analyses literature, to compare with my chosen article.
Do a comparative analysis with the other 2 articles to prove the results of data analysis of the assigned article. How to filter and prove the same and different parts

Focus on 1. What is the Effect size? 2. Fixed or random-effects model to estimate the effect size? 3. Preferences 4. Heterogeneity
