    d. sample statistic

    See explanation below

    Step-by-step explanation:

    Let's analyze one by one the possible options.

    a. population parameter.

    FALSE, a population parameter is a quantity that is related about an entire group or population and not for the sample

    b. sample parameter.

    FALSE, the sample can't be a parameter since we obtain statistics from sample and parameters from population.

    c. population mean.

    FALSE, the population mean is a parameter and is related to the population and not for the sample

    d. sample statistic

    TRUE, by definition a sample statistic is any quantity that we can derive from a sample selected from a population (some examples are the sample mean, sample deviation, sample median)

    So then we can conclude that a summary value obtained from the sample is known as: sample statistic.
