Let {X1, X2, X3, ..., Xn, Xn+1} be IID sample from a normal population with mean u and standard deviation d, show that: Var(Xn+1 - x-barn) = ((n+1)d2)/n Note: x-barn is the sample mean, as I could not get the symbol; and d is the popolation standard deviaton as I could not get the symbol; also, d2 is the variance.
