A newborn baby has extremely low birth weight (ELBW) if it weighs less than 1000 grams. A study of the health of such children in later years examined a random sample of 219 children. Their mean weight at birth was x̄ = 810 grams. This sample mean is an unbiased estimator of the mean weight in the population of all ELBW babies, which means that
|
|
In all possible samples of size 219 from the population, the mean of the values of will equal 810.
|
|
|
In all possible samples of size 219 from this population, the mean of the values of will equal
|
|
|
As we take larger and larger samples from this population, x̄ will get closer and closer to
|
|
|
In all possible samples of size 219 from the population, the values of will have a distribution that is close to Normal.

The person measuring the children’s weights does so without any error.
