Employee_Salary_Data_Set.xls 

this is the workbook needed, the first tab is the data to answer the questions with, the week 3 tab is the questions I need help with, I right click to open with excel because apparently I do not have this version, you might, its only 6 or 7 questions usually....answer them on the same tab as the questions, just make space or insert cells to make room, you can look at tab for week 1(2) as I already did those questions and turned the answers red...thanks
