Hi,
I ‘d like to thank Mr.Jay Warner for replying to my post as below.

Seriously, if you use proper random number generators in the distribution value generator, all
should be well.
I use Excel to generate a normal dist., and a spread sheet to generate an F dist., so my students
can see the distribution develop for themselves.
In Excel, the function for the normal is:
=NORMSINV(RAND())
and away it goes!
for the F, which we used last night, I have a sheet which does the above function 60 times, 30 in
each of two columns. Then it computes the F ratio, s(1)^2/s(2)^2. I have the students
recalculate this 100 times, and put the numbers into a histogram.
Same for the normal dist., as well.
Is this what you are discussing? If so, the trick is then to find the 'inverse' function for the
distribution you want.
