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.
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?
