I want right answer

Let Y be a random variable with mean zero and variance o². What do we know about the quantity 2-1 (Yi – 7) where - n i=1 Y = ! E" Y; ? i=1 It is a good estimator for the population variance. It is equal to zero in any sample. It is normally distributed with mean zero and variance o². It is normally distributed with mean zero and variance o2/n .
