susumandri,Given two sets of 50 coin tosses,
how would you tell if one set is fake or real?
Please tell me a method. I remember seeing a formula once,
but unfortunately i have forgotten
Sorry everyone, the above is what I was really looking for !susumandri,
if you really had a serious question regarding this idea, then I would have expected
you to have formulated it such as this:
"Given two sets of 50 coin tosses, one done experimentally and the other 50 chosen
off the top of your head, which set(s) of coin tosses would be indicative of a fair coin?"
If a set of 50 coin tosses (actual or conjured up) would deviate "too much" **
from an average of 25 heads and 25 tails, then I would state that that
set of 50 tosses indicates that you aren't using a fair coin.
** On average, for a "large number" of tosses of a fair coin, the proportion of
heads to tails will more so even out.
Please type a question as originally posed by an instructor and/or a textbook,
for serious consideration.
