Because there are 250 players in the league, she chooses the names of 50 of the players and asks then whether they also play soccer. Describe the population and sample. What is the size of the population and what is the size of the sample? Show your work.
Population: The entire group of people who play in the softball league.
- Size of the population: 250 players
Sample: The subset of the population that Marta chooses to ask about playing soccer.
