**Determine whether the given value is a statistic or parameter.**
A health and fitness club surveys 40 randomly selected members and found that the average weight of those questioned is 157 lb.
- o parameter
- o statistic
**Explanation:**
---
- **Parameter:** A parameter is a numerical value that describes a characteristic of a population.
- **Statistic:** A statistic is a numerical value that describes a characteristic of a sample.
In this scenario, since the health and fitness club surveyed a sample of 40 randomly selected members from the club, and provided the average weight of those members, the value given (157 lb) is a statistic because it summarizes a characteristic of a sample, not the entire population.
