**1. EA Sports is interested in how much money, on average, their customers spend on in-game items. Using their records, they draw a sample of 10,000 customers and calculate each customer's average spending on in-game items.**
**A. Identify the population, sample, parameter, statistic, variable, and data for this example.**
I. Population
II. Sample
III. Parameter
---
**Explanation:**
This text is part of a statistics educational exercise focusing on identifying key statistical concepts in a real-world context:
- **Population** refers to the entire group of individuals or instances about whom we seek information; in this case, all EA Sports customers.
- **Sample** is a subset of the population that is used to gather data; here, the sample consists of 10,000 EA Sports customers.
- **Parameter** is a numerical summary of a population.
- **Statistic** is a numerical summary of a sample, calculated for inferential purposes.
- **Variable** is the characteristic or measurement of interest; in this scenario, it's the average spending on in-game items.
- **Data** are the collected measurements or observations about the variable from the sample.
