Multiple Regression
Discussion: Multiple RegressionAs with the previous week’s Discussion, this Discussion assists in solidifying your understanding of statistical testing by engaging in some data analysis. This week you will once again 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.By Day 3Use 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.

Read the Chapter 9 Case Study "Facility Layout at Wheeled Coach Ambulance" and watch the video, then write a summary of at least 300 words using the accompanying discussion questions to guide your essay written in APA style, with a reference page and a cover page.https://www.mathxl.com/Student/MediaPopup.aspx?typ...Facility Layout at Wheeled CoachWhen President Bob Collins began his career at Wheeled Coach, theworld’s largest manufacturer of ambulances, there were only a handful ofemployees. Now the firm’s Florida plant has a workforce of 350. Thephysical plant has also expanded, with offices, R&D, final assembly,and wiring, cabinetry, and upholstery work cells in one large building.Growth has forced the painting work cell into a separate building,aluminum fabrication and body installation into another, inspection andshipping into a fourth, and warehousing into yet another. Like many growing companies, Wheeled Coach was not able to design itsfacility from scratch. And while management realizes thatmaterial-handling costs are a little higher than an ideal layout wouldprovide, Collins is pleased with the way the facility has evolved andemployees have adapted. The aluminum cutting work cell lies adjacent tobody fabrication, which, in turn, is located next to the body-installation work cell. And while the vehicle must be driven across astreet to one building for painting and then to another for finalassembly, at least the ambulance is on wheels. Collins is alsosatisfied with the flexibility shown in design of the work cells. Cellconstruction is quite modular and can accommodate changes in product mixand volume. Additionally, work cells are typically small and moveable,with many work benches and staging racks borne on wheels so that theycan be easily rearranged and products transported to the assembly line.Assembly-line balancing is one key problem facing Wheeled Coach andevery other repetitive manufacturer. Produced on a schedule calling forfour 10-hour work days per week, once an ambulance is on one of the sixfinal assembly lines, it must move forward each day to the nextworkstation. Balancing just enough workers and tasks at each of theseven workstations is a never-ending challenge. Too many workers end uprunning into each other; too few can’t finish an ambulance in 7 days.Constant shifting of design and mix and improved analysis has led tofrequent changes.Discussion Questions*1. Develop a layout model for Wheeled Coach. Include in your model eachstep in the process. Assigned the steps with predecessors. Use minutesas your time increment. Calculate a cycle time, theoretical time,balance the line using the longest task time rule and determine theefficiency from your simulated data. 2. What other analytical techniques are available to help a company like Wheeled Coach deal with layout problems?3. What suggestions would you make to Bob Collins about his layout?4. How would you measure the “efficiency” of this layout?

Quadratic Equations and Prime Numbers
Solving the quadratic equations using the FOIL method makes the equations easier for me to understand. The Foil method, multiplying the First, Outer, Inner and Last numbers, breaks down the equation a little further so you understand where some of your numbers are coming from, plus it helps me to check my work. Equation (a.) x^2 – 2x – 13 = 0
