Confidence Intervals
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 titleThe salary (in dollars) for each jobYou 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 DataThe 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 SubmitYour 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.

MATH145 Unit 3 Algebra Problem Situation Maximum Storage Area Project
Problem Situation:A construction company wishes to build a rectangular enclosure to store machinery and equipment. The site selected borders on a river that will be used as one of the sides of the rectangle. Fencing will be needed to form the other three sides. The company has 682 feet of 10-foot high chain-link fencing. The questions that follow should help you determine the dimensions of the rectangle that will produce the maximum area for the storage site. Assume that the company wishes to use all of the fencing, and that “width” refers to the measure of each of the two sides that are perpendicular to the river, and “length” refers to the measure of the side parallel to the river (see diagram). For the questions that follow, all measurement answers are to be given with the correct unit label, e.g. feet, square feet, etc. All of the questions are in the file

Confidence Interval for Population Mean, homework help
Please help me with this. It does not need to be rocket science it needs to be at a stats novice level and easy to understand. thank you.:Using a sample to create a range or interval of values that estimates a population value is called a “confidence interval.” The formula for calculating a 95% confidence interval for a population mean is: Confidence Interval for Population Mean: sample mean – E < population mean < sample mean + E Error “E” = (1.96)*(s) / sqrt(n) “s” is the standard deviation and “n” is the sample size. Part 1: Confidence Intervals Why is it often impossible to know the actual value of any population parameter? Give an example of a population parameter that you cannot calculate, but that you can estimate. A sample can be used to estimate a population parameter. How does the sample size affect the estimate? If the sample is larger, what will this do to the error E? Use the Confidence Interval formula above and calculate the 95% confidence interval for any population mean of your choice. Write down (invent) the sample size (be sure it is 30 or above), the sample mean, and the sample standard deviation. Then, calculate the confidence interval. Remember, you are inventing all the values, so no two posts should look the same. Use Excel and your invented values to calculate the confidence interval. Include and compare the results.
