I tried using the for (i..) to make 1000 differents sets of numbers, but then
I dont know how to get the mean value of all of them... because I dont even
think 1000 different sets of numbers were made, because when i print it it
always shows me the same values, basically I dont know how to replicate the
funcion many times.
