1. Determine the correlation between glucose, triglycerides, TC, LDL & HDL levels.Insert correlation table.Which correlation procedure (Pearson or Spearman) did you choose and why? Which correlation is the most positive? Is this a weak, moderate, or strong correlation?Which correlation is the most negative?Write an overall interpretation of the correlation findings that addresses the strength, direction, and significance of the correlations. Run a linear regression for total cholesterol with LDL as a predictor.Is the model significant? How can you tell (provide objective data)?What is your dependent variable?What percent of TC is explained by LDL?Write a regression equation to predict TC based on LDL.Use your regression equation to predict my TC if my LDL is 145. (show equation and answer)What range of TC do you expect would give you 95% accuracy of prediction for someone with an LDL of 145?Insert regression tables to support answers Run a linear regression for HDL with both triglycerides and gender as predictors Is the model significant? Which independent variable contributes most to the equation?What is the coefficient of determination value?What percent of HDL is explained by these 2 variables together?Insert regression table to support answers.Write a summary statement describing your findings

Would you add any steps to make rational equations easier to complete or understand? 2. Give an example of a rational equation with all steps 3. What constitutes a rational expression? How would you explain this concept to someone unfamiliar with it? 4. Give an example of a rational expression with all steps

Discussion

Euler math discussionIn the 1960s, Kwan Mei-Ko, a Chinese mathematician, discovered the Chinese Postman Problem (CPP). The CPP arose from a dilemma faced by Chinese postmen delivering mail in the city. The postmen wanted to travel along every road in a city to deliver letters covering the least possible distance. The problem at hand was how to find the shortest walk to touch every edge or every location at least once. Within graph theory, a Euler cycle in a connected graph resembles the CPP.Describe in detail a real life example of the CPP. This would include any situation in which there are various points that must be touched in a path, and the goal is to touch each path using the shortest distance possible.Your initial posting should be 250-500 words and must be submitted by midnight Thursdayof this week

STATS RESEARCH PROJECT

Directions:Working from the topic chosen earlier in the Topic Selection assignment, you will be designing your own statistical study. USE ATTACHED POINT AS TOPIC TO WRITE ON In a 1250–1500 word report, discuss the design of an experiment that would expand on or relate to the research in the previously chosen article. Be sure to include the following:Background information explaining the importance of the research (why it should be done) and what has been done in the pastSampling and experimental design with rationaleData analysis techniques (specific inferential test that would need to be used and why, include tests that would need to be done to validate the assumptions needed for the chosen inferential test)Expected results as well as the questions this research will serve to answerSuggestions for future researchA minimum of four (4) additional scholarly resources are required.

Assignment 1

The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered.To support your work, use your course and text readings and also use the South University Online Library. As in all assignments, cite your sources in your work and provide references for the citations in APA format. Make sure all references are cited in APA format. References should be current at least within the last 5 years. Remember that references should be used to support your peer responses. Statistics for Contingency TablesThe purpose of this assignment is to learn about categorical data and the statistics used to analyze this type of data.You can expect to research and provide your own definitions of these concepts. You will also discuss in what situations to use each statistic, how these statistics are used to test for significance of relations among the data, and how to interpret each statistic. The takeaways from this assignment are an understanding of contingency tables as a representation of categorical data, two statistics used to analyze this type of data, and an understanding of how to interpret these statistics in the context of a public health analysis.Using the South University Online Library, the Internet, and your text readings, research the following statistical topics:Contingency tablesThe chi-squareFisher's exact test (FET)On the basis of your research, respond to the following:Find and state a definition of a contingency table that you feel is easy to understand.In your own words, explain what contingency tables are and what they are used for.Explain what type of data is displayed in contingency tables.Explain how contingency tables and their related statistics are used to test for significance of relations among the data.Two statistics that can be used in contingency tables are chi-square and FET. Distinguish between the two statistics.Explain when you would use the chi-square and when you would use the FET.Explain how you would interpret each statistic

Math quiz

Once you click the Assignment icon above, you will find links to Quiz 4, provided in two formats, a Word document and a PDF. You may type your work into the Word document, either using an equation editor or plain-text formatting, or you may write your work by hand and scan it.Please remember to show all work following standard mathematical practice:1) Each step should show the COMPLETE expression or equation, not just a piece of it.2) Each new step should follow logically from the step above it, following rules of algebra.3) Each new step should be beneath the previous step.4) The equal sign, =, should only connect equal numbers or expressions. due tonight - need by 8pm
