MIS 690 Grand Canyon University Data Needs Identification and Acquisition HW
For this assignment, you will use the "Business Problem Statement" template to organize your problem statement. This will help you identify your business problem you will eventually address using analytics. The business problem statement will be an integral component of the remaining activities in this course.Ensure that data are available to address your business problem. You will need to provide your dataset as a part of the Topic 3 assignment. If data are used from your company, ensure that proprietary concerns are addressed or approvals to use the data are obtained. If company data are being used and if there are concerns of proprietary issues, you can change your dataset accordingly.APA style is not required, but solid academic writing is expected.This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.You are required to submit this assignment to LopesWrite. Refer to the LopesWrite Technical Support articles for assistance. You can use any company (real or imagined) as a scenario. The goal is to work through the processes in the class.The choice of your business problem is critical in this class because it is the integral component to the remaining activities in the course. You must also pick a problem with which you also have access to data. If the data is used from your company, you MUST ensure that any proprietary concerns are addressed and approvals to use the data are obtained. One step that we can easily take is that of anonymizing the data by removing all references to specific individuals or organizations.There are many business problems that can be addressed using public datasets such as those at data.gov. If company approval is not likely, I would suggest that you search for a public dataset that can serve as the basis for your analysis.If there continue to be issues with obtaining the data after you define your business problem, we can always adjust your business problem to a dataset that is more accessible.Does the scenario you provided work, will you be able to provide data set to further the process?

SU Multiple and Linear Regression for Amazon Net Income Analysis
First part: Linear Regression Analysis
Terry Downes owns a commercial cleaning company. He has conducted a survey of customers to determine how satisfied they are with the work performed. He devised a 100-point rating scale—with 0 being poor and 100 being excellent service, selected a random sample of 14 customers, and asked them to rate the service. He also recorded the number of worker hours spent in the customer's facility. These are in the file named Downes.
Use Excel to complete the following:
Develop a scatter plot showing the variables, rate of service and worker hours, with the y variable on the vertical axis and the x variable on the horizontal axis, and indicating the type of relationship.
Develop a linear regression model to explain the variation in the service rating.
Use Word to complete the following:
Describe the model, showing the results of the pertinent hypothesis tests, using a significance level of 0.10.
Submit your work in a Word document and attach your Excel file.
second part: Multiple Regression Analysis
Amazon.com has become one of the most successful online merchants. Two measures of its success are sales and net income/loss figures. The data can be found in the file, Amazon.
Use Excel to complete the following:
Construct a scatter plot for Amazon's net income/loss and sales figures for the period 1995–2015.
Determine a polynomial model, including its order (or degree), for Amazon's net income/loss and sales figures.
Use Word to complete the following:
Explain your process of determining the polynomial model

Evaluate hypothesis tests for population parameters from two populations. Dealing with Two Populations
Inferential statistics involves forming conclusions about a population parameter. We do so by constructing confidence intervals and testing claims about a population mean and other statistics. Typically, these methods deal with a sample from one population. We can extend the methods to situations involving two populations (and there are many such applications). This deliverable looks at two scenarios. Concept being Studied
Your focus is on hypothesis tests and confidence intervals for two populations using two samples, some of which are independent and some of which are dependent. These concepts are an extension of hypothesis testing and confidence intervals which use statistics from one sample to make conclusions about population parameters. Student
