I have a value

How to find a p-value from this. I need to show that "a" is different fom
mean(x).
Thanks
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.
