Answer:
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.
