The standard deviation of the sample of distances traveled by the 5 employees is approximately **15.25 miles**, rounded to two decimal places.

Do you want more details or have any further questions?

Here are 5 related questions to deepen your understanding:
1. How would you calculate the variance for this sample of distances?
2. What is the difference between population standard deviation and sample standard deviation?
3. How does the standard deviation change if one of the distances is much larger than the rest?
4. Why do we subtract 1 (using "n-1") when calculating the sample standard deviation?
5. How does the standard deviation help in understanding the spread of data?

**Tip:** In any data set, the larger the standard deviation, the more spread out the data is from the mean!

The following are distances (in miles) traveled to the workplace by 5 employees of a certain hospital: 40, 36, 9, 18, 7. Find the standard deviation of this sample of distances. Round your answer to two decimal places.

Learn how to find the standard deviation for a sample of distances traveled to work by 5 employees of a hospital. This problem explores statistical concepts such as the sample mean, variance, and standard deviation. The data points are 40, 36, 9, 18, and 7 miles, and the answer is rounded to two decimal places.
