2. Review on estimators. Let Y = (Y1, 2, 3, 4) be a random sample from the normal distribution N(μ, 2²), where the expected value of the normal distribution μER is unknown, and the variance parameter has four (4) as a value. We examine the following parameter μ estimator 1 ₪ (Y) = ± ± (Y₁ + Y₂ + Y3 + 2Y₁) 4 Calculate the bias of the estimator (Y). Is the estimator unbiased? Calculate the variance and the mean squared error (MSE) of the estimator. The problems deal with the confidence intervals (Chapter 5 topics) and especially testing theory (Chapter 6).
