    Unbiased estimator

    ImageShack® - Online Photo and Video Hosting


    I have done part i and ii, and I am stuck on part iii.

    How do I show it is an unbiased estimator?

    Thanks.

    find its expected value. it should be \alpha + 10\beta.

    If you want more detail than that, tell us what your proposed estimator is.

    use \hat\alpha +10\hat\beta where

    \hat\alpha,\hat\beta are the usual estimators of \alpha,\beta
