Your manager is looking for your recommendations for how the store could best respond to: declining sales, reducing staffing, and purchasing the building.To do this, download and fill out the Calculations and Report Document (attached).As you complete part one of this document, break down each of the three problems individually. When representing problems as expressions, don’t be afraid to try a few equations for each step to see what works. Use information and data from the company files in the “Supporting Materials” section to answer the questions.In part two, give your recommendations to your manager: what do you think the company should do about declining sales, reducing staffing, and purchasing the building? Be sure to support your recommendations with quantitative evidence. Then, explain how you used mathematical expressions to solve these problems.When you have completed both parts of the Calculations and Report Document, you can submit it as your deliverable.All materials needed have been attached.

THE ANSWER MUST BE ORIGINAL AND NOT FROM ANOTHER STUDENT'S PAPER Use the sources provided in the details to answer the question and use this scenario to answer the question:  Reducing the Readmission of Patients Discussion: Building Regression Models in Health Care Finding evidence-based relationships among variables is an important tool for any healthcare administration leader. On a daily basis, healthcare administration leaders may want to see what variables are correlated so that they can implement quality improvement. This week, you think of scenarios where building and interpreting regression models would be useful for healthcare administration leaders. You might consider building off of your Week 4 Discussion. For example, Jenna, a healthcare administration leader, determined last week that patient satisfaction scores had fallen from the mean of 87. She wants to know why. She believes that it may have something to do with patient waiting time and time spent with the doctor. Thus, her dependent variable (y) is patient satisfaction and the independent variables are waiting time (x1) and time spent with the doctor (x2). She can evaluate the relationship between these two variables using correlation; bivariate scatterplots for y vs. x1 and y vs. x2; and regression techniques. For this Discussion, think about a healthcare scenario where multiple regression might be useful in your organization or one with which you are familiar. Consider what your dependent and independent variables might be for conducting a multiple regression analysis. Build a small example, and run the regression analysis. By Day 3 Post a description of the dependent and independent variables you will use for your multiple regression analysis, and then explain your regression model in terms of your dependent and independent variables. Explain how you might measure your variables. Be specific and provide examples. Required Readings Albright, S. C., & Winston, W. L. (2017).
