Please answer as fast as possible. Please answerall parts of the question and round answers tothree decimal points.2) A random sample of 50 is taken from a population with the following distribution:YPr (Y)0.40.6a) An estimator of the mean of the above distribution is specified as: A = Yı + (2/n), where Yı is thevalue of the first observation in the sample and n is the sample size (equal to 50). Show whether thebias of this estimator is equal to zero (0).b) Use the same probability distribution as given above, show whether the estimator Ã = Y1 + (2/n) ismore efficient than the estimator Y (the sample mean), wheren is equal to 50.c) Show whether the estimator Ã=Y1 + (2/n) is consistent.
