![### Monthly Phone Usage Data Analysis
A cellular phone company monitors monthly phone usage. The following data represent the monthly phone use in minutes of one particular customer for the past 20 months. Use the given data to answer the following questions.
#### Monthly Phone Usage Data (in minutes):
- 334, 369, 473, 538, 443
- 506, 385, 542, 407, 336
- 330, 497, 422, 445, 460
- 372, 447, 449, 358, 455
---
#### Analysis:
**Determine the standard deviation and interquartile range of the data.**
**s =** [ ] (Round to two decimal places as needed.)
**IQR =** [ ] (Type an integer or a decimal.)
This data helps in understanding the variability and distribution of phone usage over the specified period. Calculating the standard deviation and interquartile range provides insights into the spread and central tendency of the data.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F358f2374-ec0b-47e3-b3ef-a3300df189bd%2Fa03e000a-b8d2-4ac9-86cd-7873d4888a0f%2Fjkbgtc_processed.png&w=3840&q=75)
