Let Y be a normal random variable with mean μ and variance σ 2 . Assume that μ is known but σ 2 is unknown. Show that (( Y - μ )/ σ ) 2 is a pivotal quantity. Use this pivotal quantity to derive a 1- α confidence interval for σ 2 . (The answer should be left in terms of critical values for the appropriate distribution.)
