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.
What to Submit
Your boss wants you to submit the spreadsheet with the completed calculations. Your research and analysis should be present within the answers provided on the worksheet.

A retail company must file a monthly sales tax report listing the sales for the month and the amount of sales tax collected. Write a program that asks for the month, the year, and the total amount collected at the cash register (that is, sales plus sales tax). Assume the state sales tax is 4 percent and the county sales tax is 2 percent.
If the total amount collected is known and the total sales tax is 6 percent, the amount of product sales may be calculated as:
S = T/1.06
S is the product sales and T is the total income (product sales plus sales tax).
The program should display a report similar to the following. Be sure and read the section of setprecision(),setw() and use these formatting options for the output.
Month: October
----------------------------
Total Collected: $ 26572.89
Sales: $ 25068.76
County Sales Tax: $ 501.38
State Sales Tax: $...1002.75
Total Sales Tax $ 1504.13
