Maritza plays in a softball league. She wants to know about how many players in the league also play basketball. Because there are 225 players in the league, she chooses the names of 45 of the players and asks them whether they also play basketball. Describe the population and the sample. What is the size of the population, and what is the size of the sample? Show your work.
(explain it in 7th garder words)
The population in this situation is all 225 players in the softball league. Maritza is taking a sample of 45 players from the population to ask them about playing basketball. The size of the population is 225 players, while the size of the sample is 45 players.
explanation with equations
In this scenario, the population size (N) is 225 players, and the sample size (n) is 45 players.
Population size (N) = 225
Sample size (n) = 45
No, I meant, hw can you explain that the answer is 45
To determine the sample size of 45 players that Maritza chose to ask about playing basketball, we can use a common method called random sampling. Random sampling involves selecting individuals from a population in a way that each member of the population has an equal chance of being selected for the sample.
In this case, Maritza chose to survey 45 players out of 225 in the softball league. This sample size of 45 players was likely chosen to be representative of the entire population, allowing her to make an inference about the entire league based on the responses of the 45 selected players. Selecting 45 players out of 225 ensures a manageable sample size while still providing enough data to draw conclusions about the whole league.
