This question doesn't really make sense.  sample(1:50) gives you the 
same sample as 1:50 does, just in a different order.  So the mean is 
guaranteed to be 25.5, which is obviously different from 300.

If you really did have a random sample from some unknown distribution 
and you wanted to test whether the mean of that distribution is 
different from 300, then Henrik's suggestion is reasonable for most 
distributions.
