isida An unbiased estimator is one for which the expected va;ue of the estimator is equal to the parameter you are trying to estimate. so, if the expected value of the sample mean is equal to the population mean, the sample mean is an unbiased estimator of the population mean.
Shammel Why exactly is A and C wrong?
thekid C is wrong b/c it says "a LOW standard of error", it should be "a ZERO standard of error"

BUT..

I have no clue why 'A' is incorrect!
Jurrens this is a "choose the best answer" question
johntan1979 It is EQUAL, no longer a point estimate.
thevinu But B too says Estimate
