Transcript text: Determine whether the value is a parameter or statistic
$20 \%$ of vehicles sold are compact cars
Solution
Solution Steps
To determine whether a value is a parameter or a statistic, we need to understand the context of the data. A parameter is a value that describes a characteristic of a population, while a statistic describes a characteristic of a sample. In this case, if the 20% refers to all vehicles sold (the entire population), it is a parameter. If it refers to a sample of vehicles, it is a statistic.
Step 1: Understanding Parameter vs. Statistic
To determine whether \( 20\% \) of vehicles sold being compact cars is a parameter or a statistic, we need to clarify the context. A parameter describes a characteristic of the entire population, while a statistic describes a characteristic of a sample.
Step 2: Analyzing the Given Information
The statement "20% of vehicles sold are compact cars" does not specify whether it refers to all vehicles sold (the population) or just a sample of vehicles. Without this context, we cannot definitively classify the value.
Step 3: Conclusion
Since the description lacks clarity on whether it pertains to the entire population or a sample, we conclude that it is "Unknown" in terms of classification.
