If you are being asked "What can you say about the unbiasedness, consistency and efficiency of these three estimators?" you must have seen the "E(.)", ie expectation or something. Use that.

If this all is not ringing bell, I wuld just drop the class, and go back-packing or something fun.

Dear fed2,
I know that I have to use the expected value to calculate the means, but I don’t know how to do it in this case (without sample)
