Homework Help: Biased estimator

  1. Oct 21, 2008 #1
    1. The problem statement, all variables and given/known data

    The reading on a voltmeter connected to a test circuit is uniformly distributed on the interval (a, a+1) where a (unknown) is the true voltage. Let Y1, Y2, Y3,...,Yn denote a random sample of such readings.
    show that Y(bar) is a biased estimator for a.
    and find an unbiased estimator for a expressed in terms of Y(bar)

    2. Relevant equations

    3. The attempt at a solution

    i have no idea how to do thus question so any help would be v much appreciated.
    Thank you
