Based on the information given, the statistics that appear to be unbiased estimators of the population parameter is statistics A.
<h3>
Solving the statistics.</h3>
It should be noted that statistic A is the unbiased estimator of the population parameter. This is because it's centered around the population parameter which is 75.
The statistic that would be a better estimate of the population parameter is statistic A. This is because the sample mean is equal to the population mean which is 75.
The statistic that would be a better estimator of the population parameter is statistic D since it's equal to the population means.
Lastly, it should be noted that statistic C has no distribution shape.
