Re: Sampling Distribution

Hey rokman54.

X_bar and S^2 should be independent so there will be nothing in common between the those two events. If there is then you can't use the common distributional assumptions (like a t-test for example).

If X_bar and S^2 are dependent on each other than you should not have a Normal distribution (in relation to the same way that mu and sigma^2 are independent parameters).

Re: Sampling Distribution

Thanks.

Also I figured out how to do the second : a simple t distribution.
