Hi I Am Enrolled In Bus 308 Statistics For Managers At Ashford University

Hi I am enrolled in BUS 308, Statistics for Managers at Ashford University. I am having a difficult time with the assignments for Week 2-Week 4. 

Please see the link below with the necessary spreadsheet:

The assignment needs to be completed by using an excel document and keeping the formulas accurate. The first two tabs of the assignment is the data info that is needed to complete the assignment correctly. If you cannot assist with all the tabs, I am happy to open another question for the rest of the assignments. Thank you.
