The instructions for what to do are listed in boxes of merged cells, starting in each case at the cell range K1:Q1. Follow the instructions on each of the 4 sheets to complete the assignment. All work must be your own.
Make sure you save all files as Excel files (not Numbers files, PDF files, or something else like that) and upload them at the link provided here. If you must, use a school computer with a full version of Excel in order to complete your work.
Please note that I will need to see evidence of use of Excel’s capabilities within your file, so don’t compute things elsewhere and insert them manually. Also, as always, ensure that your results are all listed with consistent, appropriate precision. In the cases that you have to write analysis, make sure to use units as appropriate.
