Try to explain first in English what you are doing, before jumping into formulas. For example “Next, I will calculate the cofactors of each element of the coefficient matrix”, “I will expand the determinant by the third row”, etc.... You are answers should be in ONE PDF file (that is ONE file, and it is not a JPG, HEIC or whatever other format).

Week 8 Discussion: RegressionRequired ResourcesRead/review the following resources for this activity:Textbook: Chapter 12 (All Sections)LessonMinimum of 1 scholarly sourceInitial Post InstructionsMedical professionals can find relationships between variables. The more you drink alcohol, the less functionality of your liver. The less carbohydrates a person intakes, the lower their Body Mass Index.Data can be collected and organized as an ordered pair (x, y). The data can be analyzed to determine the type and strength of a correlation and to calculate a regression line in order to make a prediction.Use the internet to find a data set of ordered pairs. Key terms to search: Free Public Data Sets and Medical Data Sets.Create a Post:Introduce your Data Set and Cite the Source.Which would be the independent variable, and which would be the dependent variable?Without drawing a scatter plot, would you expect a positive, negative or no correlation? Explain.Would you categorize your data to have a strong or weak correlation? Why?What would the r2 value tell you about the data that you selected?What is the equation of the regression line?Use the regression line to make a prediction about the data you collected.Follow-Up Post InstructionsRespond to at least two peers or one peer and the instructor. Further the dialogue by providing more information and clarification.Here are suggested responses.Review the data of a peer. List the parts of the analysis that you agree with and why. Ask one clarifying question.Compare the analysis of two pieces of data until you find two that have a similar report. What are the subjects of those reports and why do you think they would have the same analysis?Writing RequirementsMinimum of 3 posts (1 initial & 2 follow-up)APA format for in-text citations and list of referencesGradingThis activity will be graded using the Discussion Grading Rubric.

During the global recession of 2008 and 2009, there were many accusations of unethical behavior by Wall Street executives, financial managers, and other corporate officers. At that time, an article appeared suggesting that part of the reason for such unethical business behavior may stem from the fact that cheating has become more prevalent among business students. The article reported that 86% of business students admitted to cheating at some time during their academic career as compared to 77% of non-business students.Cheating has been a concern of the dean of the College of Business at Rocky University for several years. Some faculty members in the college believe that cheating is more widespread at Rocky than at other universities, while other faculty members think that cheating is not a major problem at the college. To resolve some of these issues, the dean commissioned a study to assess the current ethical behavior of business students at Rocky. As part of this study, an anonymous exit survey was administered to a sample of 90 business students from this year’s graduating class. Responses to the following questions were used to obtain data regarding three types of cheating.During your time at Rocky, did you ever present work copied off the internet as your own?____ Yes____ No During your time at Rocky, did you ever copy answers off another student’s exam?____ Yes____ No During your time at Rocky, did you ever collaborate with other students on projects that were supposed to be completed individually?____ Yes____ NoAny student who answered yes to one or more of these questions was considered to have been involved in some type of cheating. The complete data set is in the file named Rocky, linked at the bottom of the page.Managerial ReportPrepare a report (see below) for the dean of the college that summarizes your assessment of the nature of cheating by business students at Rocky University. Be sure to include the following seven (7) items in your report.To summarize the data, compute the proportion of all students, the proportion of all male students, and the proportion of all female students whopresented work copied off the internet as their owncopied answers off another student’s examcollaborated with other students on projects that were supposed to be completed individually. Then comment on your findings.Develop 95% confidence intervals for the proportion of all students, the proportion of all male students, and the proportion of all female students who were involved in some type of cheating.Develop 95% confidence intervals for the proportion of all students, the proportion of all male students, and the proportion of all female students who were involved in copying off the internet.Develop 95% confidence intervals for the proportion of all students, the proportion of all male students, and the proportion of all female students who were involved in copying off another's exam.Develop 95% confidence intervals for the proportion of all students, the proportion of all male students, and the proportion of all female students who were involved in collaborating on an individual project.Conduct a hypothesis test (using either the p-value approach or the critical value approach) to determine if the proportion of all business students at Rocky University who were not involved in some type of cheating is less than that of all business students elsewhere. Use α = 0.05. Do not forget to include the correctly worded hypotheses.What advice would you give to the dean based upon your analysis of the data? Focus your advice on answering the following: What is the magnitude of the issue? What would you recommend for both students and faculty? What is the potential impact on relationships with the business community and what would you recommend? How can this study be improved?Write a report that adheres to the Written Assignment Requirements under the heading “Expectations for CSU-Global Written Assignments” found in the CSU-Global Guide to Writing and APA Requirements.
