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

The client needs the preliminary findings by the end of the day. Your boss asks you to first compute some

basic statistics and then analyze the results in the four questions given in the Excel spreadsheet.

Instructions

The Excel spreadsheet contains five tabs. The first tab, labeled “data” requires you to calculate all measures of center and variation using the correct Excel formulas.The next four tabs contain questions for you

to complete. Ensure that you are completely answering all questions with explanations and that your work.

is shown when needed.

You must submit the spreadsheet with the completed calculations, answers, and analysis. Instructions
