Given that the U.S. Census Bureau needs to estimate the median income of males in the U.S, and they collect incomes from 2500 males:
• You need to remember that, by definition, Statistics is a study in which data is collected, analyzed, and then this is used to make a conclusion.
In this case, you can identify that the Statistic is the income obtained from the sample selected.
• By definition, the Population is the set of all the values or the set of all the individuals selected (the entire group).
In this case, as the U.S. Census Bureau needs to estimate the median income of males in the U.S, the population is the set of incomes of all males in the U.S.
• By definition, the Sample is a part of the Population.
In this case, the sample is the set of incomes of 2500 males in the U.S.
• By definition, the Individual is the object selected.
In this case, the Individual selected is a male in the U.S.
• By definition, the Variable is the observation obtain from the individual selected.
In this case, it is the Median income of males in the U.S.
• By definition, the Parameter is a value obtained from a population.
In this case, is the Median income of 2500 males in the U.S.

• Statistics: c.
