I can't get the LaTex to work. But the first error is the variance of the sample mean divided by the sample standard deviation. We've been haveing a hard time finding the E(1/S) and E(1/S^2)... Any ideas?
Given that we have where is unknown.
Find Where is the sample Mean, is the sample variance and is the variance.
So...
Since and are independent,
We were having a real hard time finding . Also, can the be broken up in a similar way to the other term?
Is there another way to approach this problem?
The only thing known about the random variables is that they are identically and independently distributed with population mean µ and variance "sigma squared"
