After studying Module 2: Lecture Materials & Resources, discuss the following:
Create one math story based on a mathematical concept.  Your initial post should be at least 200 words/numbers or a combination of both 
 
Additional readings must be cited, and formatted in the current APA style.
You should respond to at least two of your peers by extending or adding supplementary distinctions to their posts.

Create a Pie Chart Using software (Excel, Numbers, Google Sheets, etc.) to display the satisfaction level of the patients on the excel chart uploaded 
create the Pie Chart correctly with the appropriate number of sectors, appropriate title, and percentage callouts.  also highlight the percentage to support the answer. 

 Use JASP for this assignment. 
Use Average Grade 8 Math Proficiency as the dependent variable
Use Enrollment, Average Grade 8 English Proficiency, and Rigorous Instruction Rating as independent variables
1) Run a multiple regression test.  Address categorical variable dummy coding, test for interaction effects between Enrollment and Average Grade 8 English Proficiency by additionally including the interaction term in the analysis
2) Interpret R, Adjusted R squared, Sig in the ANOVA table, Sig(s) in the Coefficient tables
3) Is an interaction effect between Enrollment and Average Grade 8 English Proficiency detected? Explain.
4) Run an assumptions check (include all charts and tables in your writeup. APA format expected) and report the results of each of the following:
Independence: Check Durbin-Watson value to be between 1 and 3
Multicollinearity: Check VIF less than 10
Linearity: Check predicted vs residual plot for dot pattern scatter
Homogeneity: Check residual plot for consistent spread over all predicted values
Normality: Check residual histogram and QQ plot
Referencing your evidence, report which of the above assumptions are likely violated or are feasibly not violated. 

 
Numerous problems in the area of finance can be addressed by using the various
optimization techniques. These problems often involve attempting to maximize the return
on an investment while meeting certain cash-flow requirements and risk constraints.
Alternatively, we may want to minimize the risk on an investment while maintaining a
certain level of return. We’ll consider one such problem here and discuss several other
financial engineering problems throughout this text. Brian Givens is a financial analyst for
Retirement Planning Services, Inc., who specializes in designing retirement income
portfolios for retirees using corporate bonds. He has just completed a consultation with a
client who expects to have $750,000 in liquid assets to invest when she retires next month.
Brian and his client agreed to consider upcoming bond issues from the following six
companies:
The column labeled “Return” in this table represents the expected annual yield on each
bond, the column labeled “Years to Maturity” indicates the length of time over which the
bonds will be payable, and the column labeled “Rating” indicates an independent
underwriter’s assessment of the quality or risk associated with each issue. Brian believes
that all of the companies are relatively safe investments. However, to protect his client’s
income, Brian and his client agreed that no more than 25% of her money should be invested
in any one investment and at least half of her money should be invested in long-term bonds
that mature in 10 or more years. Also, even though DynaStar, Eagle Vision, and OptiPro
offer the highest returns, it was agreed that no more than 35% of the money should be
invested in these bonds because they also represent the highest risks (that is, they were
rated lower than “very good”). Brian needs to determine how to allocate his client’s
investments to maximize her income while meeting their agreed upon investment
restrictions.

1.) How do the data for each ratio compare to the cutoff points? (The ratio should be greater than 1.50.)
2)  How does each Ratio compare to the other ratios?
3) Explain why what occurred, occurred and its implications. Should the organization be concerned? Can it be corrected? How? You needed to explore the internet for information about Bay City, Texas in 2022 so that you can answer why what occurred, and its implications. 

Using the Abbreviated Budget, compute the Measures of Solvency for Bay City, Texas for 2022. 
Only use the Amended Budget FY 2022 column to compute & place those findings into the chart to create a graph.

Use the Revenue Analysis Template to display the data in your research from the Revenue Worksheet. 
Also, report the means and standard deviations as whole dollars.
After filling in the template,
Answer 3 questions:
1) Which set of data shows the highest variation and which shows the lowest variation? 
2) Which state shows the highest and lowest variations in total income and total sales tax collections?
3) Which state’s tax collections are more consistent and fluctuate the least?

Objective: The primary goal is to conduct a comprehensive study using time series econometrics. You have the flexibility to choose between two distinct paths:
Replication Study: Replicate an existing paper in the field. This involves closely following the methodology and analysis of a selected study to verify its findings and understand the robustness of its conclusions.
Methodological Extension: Alternatively, you can opt to add to an existing paper by applying a different time series method.

You will review QUANTITATIVE 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.)

                2. Not worried about the question. Read the article and write what you think about the article                  3. In the paper, most include  A. Introduction/Background,  B. Methodology,  C. Study Findings and Results, D. Conclusions.
