1.    Find the probability that a randomly selected university will be public.

2.    Find the probability that a randomly selected university will have an Admissions rate equal  to 70% but less than 80%.

3.    Find the probability that a randomly selected university will have an admissions rate below 60% given that it is a private institution.

Section 4 Confidence Intervals:  In this section you will need to construct 95% Confidence intervals of the mean and variance of all the numerical (quantitative) data.  For each please interpret the confidence interval and explain any surprising results. 

Section 5 Hypothesis Testing: In this section you will make some hypotheses about the data and then use what we learned in lecture/homework to test these hypotheses.  

1.    Is the average Admissions Rate greater than 70?

2.    Is the average Retention Rate less than 80?

3.    Is the average Graduation Rate equal to 55?

4.    Is the average Admissions Rate for Private universities the same as that for 

Public?

Scenario

According to the U.S. Geological Survey (USGS), the probability of a magnitude 6.7 or greater earthquake in the Greater Bay Area is 63%, about 2 out of 3, in the next 30 years. In April 2008, scientists and engineers released a new earthquake forecast for the State of California called the Uniform California Earthquake Rupture Forecast (UCERF).

As a junior analyst at the USGS, you are tasked to determine whether there is sufficient evidence to support the claim of a linear correlation between the magnitudes and depths from the earthquakes. Your deliverables will be a PowerPoint presentation you will create summarizing your findings and an excel document to show your work.

Concepts Being Studied

• Correlation and regression
• Creating scatterplots
• Constructing and interpreting a Hypothesis Test for Correlation using r as the test statistic

You are given a spreadsheet that contains the following information:

• Magnitude measured on the Richter scale
• Depth in km

Deliverable 6 – Analysis with Correlation and Regression.xlsx

Using the spreadsheet, you will answer the problems below in a PowerPoint presentation.

What to Submit

The PowerPoint presentation should answer and explain the following questions based on the spreadsheet provided above.

• Slide 1: Title slide

• Slide 2: Introduce your scenario and data set including the variables provided.

• Slide 3: Construct a scatterplot of the two variables provided in the spreadsheet. Include a description of what you see in the scatterplot.

• Slide 4: Find the value of the linear correlation coefficient r and the critical value of r using α = 0.05. Include an explanation on how you found those values.

• Slide 5: Determine whether there is sufficient evidence to support the claim of a linear correlation between the magnitudes and the depths from the earthquakes. Explain.

• Slide 6: Find the regression equation. Let the predictor (x) variable be the magnitude. Identify the slope and the y-intercept within your regression equation.

• Slide 7: Is the equation a good model? Explain. What would be the best predicted depth of an earthquake with a magnitude of 2.0? Include the correct units.

• Slide 8: Conclude by recapping your ideas by summarizing the information presented in context of the scenario.

Along with your PowerPoint presentation, you should include your Excel document which shows all calculations.

Do your research on statistical research methods and choose one article that used statistical QUANTITATIVE research method. Review the article and write a report following the steps below:

Your report paper should meet the following requirements:

At least the article must be peer-reviewed, full-text article that used quantitative research methods from scholarly journals.

Note: When reading an article use the PECO to analyze the paper:

• P – Population being study, techniques used in the paper
• E – Exposure (what)
• C – Control(how)
• O- outcome

The purpose of this assignment is to increase one’s knowledge base of the historical development of the different mathematical domains (CAEP A.1.4, A.2.7, A.3.10, A.4.6, A.5.6, A.6.5) and the implications for teaching. The assignment has two parts.

Part 1 requires candidates to access and evaluate/analyze researched articles on the historical development of the six mathematical domains and the contributions from diverse culture to their development (NCTM CAEP 2e.1, 4c.3, 6c.1)
Part 2 provides an opportunity for candidates to analyze and consider the research implications of the development of these domains when planning instructional activities for diverse middle or secondary classroom setting (NCTM CAEP 3b.1 3b.2, 3c.1, 3c.2, 4b.1, 4b.2, 4c.1, 4c.3, 4e.1, 6b.2, 6b.4).

See syllabus for more detailed information!

I upload the syllabus scrool the information you will see assignment and all the information that you need .

I have a probability and statistics assignment at 17:30-18:30 Est. on May 2nd, Sunday.

2-3 Confidence intervals & Hypothesis testing problems totally.

Dissertation topic : Usage of Blockchain in Supply chain management (Please let me know if you are comfortable with a different one) – I need it to be around Blockchain as that is my Major. Also, please make sure there is no plagiarism and covered the requirements with APA format.

Requirements : Need two separate papers

QUALITATIVE Journal Article Reviews

You will review both quantitative and qualitative research. The topic is up to you as long as you choose a peer-reviewed, academic research piece. I suggest choosing a topic that is at least in the same family as your expected dissertation topic so that you can start viewing what is out there. There are no hard word counts or page requirements as long as you cover the basic guidelines. You must submit original work, however, and a paper that returns as a large percentage of copy/paste to other sources will not be accepted. (Safe Assign will be used to track/monitor your submission for plagiarism. Submissions with a Safe Assign match of more than 25% will not be accepted.)

Please use APA formatting and include the following information:

• Introduction/Background: Provide context for the research article. What led the author(s) to write the piece? What key concepts were explored? Were there weaknesses in prior research that led the author to the current hypothesis or research question?
• Methodology: Describe how the data was gathered and analyzed. What research questions or hypotheses were the researcher trying to explore? What statistical analysis was used?
• Study Findings and Results: What were the major findings from the study? Were there any limitations?
• Conclusions: Evaluate the article in terms of significance, research methods, readability and the implications of the results. Does the piece lead into further study? Are there different methods you would have chosen based on what you read? What are the strengths and weaknesses of the article in terms of statistical analysis and application? (This is where a large part of the rubric is covered.)
