A normal distribution with unknown mean μ and variance 10 is sampled once, yielding the value x. A different normal distribution with mean 2μ and variance 12 is also sampled, yielding the value y. Consider the estimators for the mean of the form μ = ax + by, where a and b are real numbers. Find the expected value of this estimator in terms of a and b (type mu for μ): E(p) = 0 In order for this estimator to be unbiased, what must be the value of o in terms of a? b = With this value of b, what is the variance of this estimator in terms of a? var(p) What values of a and b yield the minimum-variance unbiased estimator for ? a = b= =
