f. Let X1, X2,., Xn be i.i.d. random variables from N(, ). We can use as an estimator of H. Find the expected value of A and if necessary adjust it to be unbiased estimator of t. Note: S is the sample standard deviation and X is the sample mean. g. Refer to question (f). Suppose = 0. Find the constant c so that degrees of freedom? CX2 follows F distribution. What are the
