![### Age (in weeks) at Which Babies First Crawl: Survey Results & Confidence Interval Calculation
The following data represent the age (in weeks) at which babies first crawl based on a survey of 12 mothers. The data are normally distributed, with a sample standard deviation (s) of 10.521 weeks. Construct and interpret a 90% confidence interval for the population standard deviation of the age (in weeks) at which babies first crawl.
#### Data:
- 54 weeks
- 29 weeks
- 11 weeks
- 36 weeks
- 42 weeks
- 44 weeks
- 47 weeks
- 35 weeks
- 56 weeks
- 26 weeks
- 37 weeks
- 28 weeks
#### Instructions:
1. **Click** the icon to view the table of critical values of the chi-square distribution.
2. **Select the correct choice below and fill in the answer boxes to complete your choice**:
- Use ascending order.
- Round to three decimal places as needed.
Options:
A. If repeated samples are taken, 90% of them will have the sample standard deviation between [box] and [box].
B. There is a 90% probability that the true population standard deviation is between [box] and [box].
C. There is 90% confidence that the population standard deviation is between [box] and [box].
#### Answer Submission:
- Fill in the computed values in ascending order.
- Round the final values to three decimal places for accurate representation.
#### Notifications:
- **Help me solve this**: Gets instant help on solving the problem.
- **View an example**: See an example similar to the current problem.
- **Get more help +**: Access additional resources and tutorials for better understanding.
Once all fields are accurately filled, click on the **Check answer** button to verify your solution.
#### Example Output:
- Answer choice selected: C
- Population standard deviation values: between [calculated lower bound] and [calculated upper bound]
