Estimating From Samples

Estimating From Samples
For this assessment, use the Excel Calculators, , you will practice applying inferential statistical analysis to two business decision scenarios. Complete both
following scenarios.
Practical Application Scenario 1

Refer to the stock you selected in Module 1 ( I will provide). Using the same downloaded data, build a 95 percent confidence interval for the daily stock volume using
your downloaded data. What does this confidence interval mean? Why might decision makers be interested in such an interval?

Practical Application Scenario 2

To complete this scenario, use the Sample Size Estimator file provided in Resources.

For the stock you selected in Module 1, what size sample would you need to bracket the adjusted daily closing price within 50 cents (for example, a margin of error of
50 cents)? Use the standard deviation from your data for your calculations, and assume this standard deviation represents the population standard deviation.

Assignment Submission

You must submit two documents. First, you must compile all your answers in a Microsoft Word file, pasting in the tables and graphics you created to demonstrate your
work (submitted as a .docx file). Second, you must upload the raw data (as a .csv file) that you used to do your analysis for the purposes of instructor replication.
Failure to upload the second file will result in a zero on the assignment until the file is submitted. Submit your report to the assignments area for grading.
