**Chi-Square Critical Values and Confidence Interval Calculation**
Use the given information to find the number of degrees of freedom, the critical values \( \chi^2_L \) and \( \chi^2_R \), and the confidence interval estimate of \(\sigma\). It is reasonable to assume that a simple random sample has been selected from a population with a normal distribution.
**Problem Statement:**
- **Data:** Platelet Counts of Women
- **Confidence Level:** 98%
- **Sample Size (n):** 23
- **Sample Standard Deviation (s):** 65.6
**Instructions:**
1. Click the icon to view the table of Chi-Square critical values.
**Input Section:**
- **df =** \( \_\_\_ \) (Type a whole number.)
**Options:**
