 The following table presents the fuel efficiency, in miles per gallon, for a sample of convertibles and a sample of sports cars. Covert 20 25 25 24 21 21 21. Sport 17 23 24 21 18 21 25. (a) Find the sample standard deviation of the mileage for the sample of convertibles. Round the answer to one decimal place as needed.

The sample standard deviation of the mileage for the sample of convertibles is 2.1 miles per gallon.

Would you like to explore more details or have any questions? Here are five related questions you might find useful:

1. How is the standard deviation calculated from a dataset?
2. What is the difference between sample and population standard deviation?
3. How would the standard deviation change if there was an outlier in the data?
4. Can you compare the standard deviation of convertibles with that of sports cars?
5. How does standard deviation relate to data spread in fuel efficiency?

**Tip:** The standard deviation tells you how spread out the values are from the mean—higher values indicate more variability.
