Let X1,...,Xn denote a random sample from a distribution. Let and let and where b does not depend on y.

Show that

So:

Kinda stuck here. Not sure what the expectation of is.

Any help would be appreciated.

Thanks for the help, but I already solved the problem by doing the following:

and I know what the expecation and variance of the sample variance (sample from normal distribution) is.

But thanks for your help none the less - Jan 11th 2010, 03:00 PMmatheagle
