Question:

A sample of 100 observations produces the following sample data:

y̅₁ = 1, y̅₂ = 2,
y'₁y₁ = 150,
y₂y₂ = 550,
y₁y₂ = 260.

The underlying bivariate regression model is
y₁ = μ + ε₁,
y₂ = μ + ε₂.

a. Compute the OLS estimate of μ, and estimate the sampling variance of this estimator.

b. Compute the FGLS estimate of μ and the sampling variance of the estimator.
