Let X₁, ..., X be a random sample from a population with mean μ, and variance of o. Let 1' m Y₁, Y be a random sample from a population with mean μ₂ and variance o. We will also assume that the Xs and Ys are independent of each other. *** X Y 7.2 9.2 6.6 6.1 5.8 7.1 7.8 7.8 8.1 7.4 8.5 8.9 9.8 9.7 8.3 7.0 8.3 14.1 12.6 11.2 1. Show that X - Y is an unbiased estimator for μ₁ - ₂. 2. Find the variance of X - Y. 3. Show whether X - Y is a consistent estimator for μ-₂. Hint: Both sample sizes must become large.
