A statistic is a number that describes a sample and a parameter is a number that describes a population.

Step-by-step explanation:

The definition of "statistic" is:

A piece of data from a portion of a population.

The definition of "parameter" is:

A value that tells you something about a population.

Using these definitions, the correct answer to the question is that a statistic is a number that describes a sample and a parameter is a number that describes a population.
