So, I have to do this homework at university, the subject is actually not related with IT or computer, etc.

Anyway, I'm using Excel (of course), I have to get a significant result in t test, I have the average value but I don't have the variables (or whatever you call them; by this I meant the values from which you later calculate the average value and so on). And I really need them :D

Can someone help me with this thing?
