I have been tutoring the mathematics for a long time. It would be easier for me to do it quickly.
hi,
I have read the two questions and I know how to solve them correctly anc completly.
My idea is this: use the MegaStat add-in of Excel and create all the graphs you need and compute all the statistical values. The will create a report explaining the results.
I have already done such work. The most recent was yesterday https://www.freelancer.com/projects/Excel/Excel-data-chart/.
I am available on private for more discussions.
Thank you for your time,
Florin
