D.

The sample statistic provides no useful information to the researcher in this situation.

Determine how to apply the fifth basic step in a statistical study in this situation. Choose the correct answer below.

A.

The researcher should use the methods of statistics to determine the quality of the estimate of the population parameter and draw conclusions based on this estimate accordingly.

B.

The researcher knows that the sample statistic is equal to the populationparameter, so he or she may draw conclusions with complete confidence.

C.

The researcher cannot draw any conclusions based on the value of the sample statistic.

D.

There is no way to determine how well the sample statistic estimates the population parameter.
