Discussion: Multiple Regression This Discussion assists in solidifying your understanding of statistical testing by engaging in some data analysis. This week you will work with a real, secondary dataset to construct a research question, estimate a multiple regression model, and interpret the results. Whether in a scholarly or practitioner setting, good research and data analysis should have the benefit of peer feedback. For this Discussion, you will post your response to the hypothesis test, along with the results. Be sure and remember that the goal is to obtain constructive feedback to improve the research and its interpretation, so please view this as an opportunity to learn from one another. To prepare for this Discussion: Review this week’s Learning Resources and media program related to multiple regression. Create a research question using the General Social Survey that can be answered by multiple regression. Use SPSS to answer the research question. Post your response to the following: What is your research question? What is the null hypothesis for your question? What research design would align with this question? What dependent variable was used and how is it measured? What independent variable is used and how is it measured? What other variables were added to the multiple regression models as controls? What is the justification for adding the variables? If you found significance, what is the strength of the effect? Explain your results for a lay audience, explain what the answer to your research question. Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style. Respond to at least one of your colleagues’ posts and comment on the following: Do you think the variables are appropriately used? Why or why not? Does the addition of the control variables make sense to you? Why or why not? Does the analysis answer the research question? Be sure and provide constructive and helpful comments for possible improvement. If there was a significant effect, comments on the strength and its meaningfulness. As a lay reader, were you able to understand the results and their implications? Why or why not? Required Readings Laureate Education (Producer). (2016g). Multiple regression [Video file].

Okay so as I said earlier, I have pretty easy questions that wouldn’t take that much time from you. I will attach the pictures of the assignment here in this message.

Traveling Salesman ProblemFor this Critical Thinking assignment, you will solve a real-world optimization problem using graph theory.Part I: Complete the following steps: Select a real-world optimization problem that is an example of the Traveling Salesman Problem (TSP). Create a graph modeling the real-world scenario corresponding to the problem. Use weights to represent the variable that you are optimizing. Find an optimal solution for the problem using the concepts studied in this module. Part II: Based on your work in Part I, discuss the following: Discuss your rationale for your choice of the real-world optimization problem. How were you able to identify that it was an example of the TSP? Why is this example relevant? Describe how you created the graph modeling the real-world scenario corresponding to the problem. Determine if the graph is complete. If so, use your graph to describe the formula for computing the number of Hamilton circuits. Explain in detail how you solved the problem. Describe a method for finding a non-optimal solution to the problem. Consider another variable that could be optimized in the problem. How would your answers to Part I be affected by this change? Discuss the advantages of using graph theory to solve this problem. Requirements:You must submit TWO files for this assignment. The first file should contain the computations, graphs, diagrams, etc., associated with the questions in Part I. This file may be formatted as a numbered list of answers. Unless stated in the problem, a narrative discussion is not required, but you must provide enough information to show how you arrived at the answer.The second file should be a 2-3-page narrative paper, written in APA format, associated with the situation described in Part II. Specific requirements for the paper are provided below:
