Using a long rod that has length , you are going to lay out a square plot in which the length of each 2. side is . Thus the area of the plot will be However, you do not know the value of , so you decide to make n independent measurements X1;X2; :::;Xn of the length. Assume that each Xi has mean 2. (unbiased measurements) and variance o^2.

Using a bar of length μ, you are going to lay out a square plot in which the length of each side will be length μ. Thus the area of the plot will be μ2. However, you do not know the value of μ and so you decide to make 15 independent measurements of the bar, {Xi : i = 1, … , n}. Assume that each Xi has mean μ (unbiased measurement) and variance σ2 = 0.4.(a)Find the bias of the random variable X_2 as an estimator for μ2.(b)For what value of k is the estimator X_2 − kS2 unbiased...
