Southern New Hampshire Week 7 Slope Coefficient for Weight Variable Questions
7-2 Discussion: Interpreting Multiple Regression ModelsDiscussion Topic Starts Jun 12, 2021 8:59 PMIn this discussion, you will apply the statistical concepts and techniques covered in this week's reading about multiple regression. You will not be completing work in Jupyter Notebook this week. Instead, you will be interpreting output from your Python scripts for the Module Six discussion. If you did not complete the Module Six discussion, please complete that before working on this assignment.Last week’s discussion involved development of a multiple regression model that used miles per gallon as a response variable. Weight and horsepower were predictor variables. You performed an overall F-test to evaluate the significance of your model. This week, you will evaluate the significance of individual predictors. You will use output of Python script from Module Six to perform individual t-tests for each predictor variable. Specifically, you will look at Step 5 of the Python script to answer all questions in the discussion this week.In your initial post, address the following items:Is at least one of the two variables (weight and horsepower) significant in the model? Run the overall F-test and provide your interpretation at 5% level of significance. See Step 5 in the Python script. Include the following in your analysis:Define the null and alternative hypothesis in mathematical terms and in words.Report the level of significance.Include the test statistic and the P-value. (Hint: F-Statistic and Prob (F-Statistic) in the output).Provide your conclusion and interpretation of the test. Should the null hypothesis be rejected? Why or why not?What is the slope coefficient for the weight variable? Is this coefficient significant at 5% level of significance (alpha=0.05)? (Hint: Check the P-value, , for weight in Python output. Recall that this is the individual t-test for the beta parameter.) See Step 5 in the Python script.What is the slope coefficient for the horsepower variable? Is this coefficient significant at 5% level of significance (alpha=0.05)? (Hint: Check the P-value, , for horsepower in Python output. Recall that this is the individual t-test for the beta parameter.) See Step 5 in the Python script.What is the purpose of performing individual t-tests after carrying out the overall F-test? What are the differences in the interpretation of the two tests?What is the coefficient of determination of your multiple regression model from Module Six? Provide appropriate interpretation of this statistic.In your follow-up posts to other students, review your peers' results and provide some analysis and interpretation:Interpret your peer’s coefficient of determination. How does it compare with yours?How do the results of your peers’ t-tests compare with yours?Would you recommend this regression model to the car rental company? Why or why not?Remember to attach your Python output and respond to all questions in your initial and follow-up posts. Be sure to clearly communicate your ideas using appropriate terminology.

SNHU Mobile Operating Systems and Foundational Concepts Discussion
In this module, you learned about mobile operating systems and foundational concepts around desktop security. For your initial post, you will discuss your understanding of these concepts. You will also reflect on your overall learning experience in this course.In your initial post, address the following:Write a brief reflection on the course concepts and what you've learned this term. Note anything that you found surprising, and the most interesting thing you learned in this course. Consider the following:
What concepts were the most intriguing or memorable?What concepts directly apply to your life now or your future?Why might these concepts be important to remember in future courses?Then answer the following questions pertaining to mobile OSes and security:What are two recent mobile phone OSes and their hardware requirements?What are some of their known vulnerabilities? How would you approach each vulnerability based on the OS of the mobile device?Based on the mobile phone device, would the Android, Apple, or Microsoft OS be more at risk than others? Why or why not?In response to two of your peers:Discuss similarities, connections, or differing opinions on what you and your peers learned in this course.Then address the following questions to build on the discussion around mobile OSes and security:Have you had any experiences troubleshooting any mobile devices, whether on your own mobile device or for a friend, family member, or colleague?If so, what was the issue and what did you do?If not, what are some issues that you may encounter and what would you do to troubleshoot those issues?Have you ever experienced malware on a mobile device?If so, what happened and what did you do to resolve it?If not, what would you do to remove the malware?
