Deliverable 3 - Confidence Intervals
Scenario (Information repeated for deliverable 01, 03, and 04)
A major client of your company is interested in the salary distributions of jobs in the state of Minnesota that range from $30,000 to $200,000 per year. As a Business Analyst, your boss asks you to research and analyze the salary distributions. You are given a spreadsheet that contains the following information:
A listing of the jobs by title
The salary (in dollars) for each job
You have previously explained some of the basic statistics to your client already, and he really liked your work. Now he wants you to analyze the confidence intervals.
Background information on the Data
The data set in the spreadsheet consists of 364 records that you will be analyzing from the Bureau of Labor Statistics. The data set contains a listing of several jobs titles with yearly salaries ranging from approximately $30,000 to $200,000 for the state of Minnesota.

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
