- We can use this example to illustrate an interesting theoretical
point about the error, and now compare two methods of finding an
error.
- (a) According to the central limit theorem, the variable
is a sum over
independent random variables and has mean 
and standard deviation 
.
- The mean and standard deviation of y refer to distribution of
values of y in many experiments--- each of n
observations.
