14.2. Let X be a random variable with expectation and variance o. Let (X1, ..., X,) be a sample of X. There are many other estimates of o2 which suggest themselves in addition to the one proposed earlier. Show that C (X+1X) is an unbiased estimate of o for an appropriate choice of C. Find that value of C. 200 X = 3754.
