let x1, x2,.....,xn constitute a random sample of size n from a distribution given by:
f(x)=(1+ax)/2 -1<= x <= 1; -1 <= a <= 1
Show that the x-bar is a biased estimator of a. Hence, deduce an unbiased estimator of a and show that this estimator is a consistant estimator of a.
Could anyone help me at all???
...Should I go back to school?
