Limit Central Theorem Notation. N (, 2) refers to normal with mean and variance 2. Have just seen that when X1, . . . , Xn} is a random sample from N (, 2) then sample means X N (, 2/n). This follows from a more general result that: 2 If Xi N (i, i ) are independent normals then any linear combination n Y = a0 + aiXi i=1 is also normal. By rules of linear combinations n E[Y ] = a0 + aii i=1 n Var[Y...
