**Understanding Critical t Values**
When conducting statistical analyses, it’s crucial to understand how to find critical t values, especially when working with small sample sizes.
**Problem Statement:**
*For a confidence level of 95% with a sample size of 23, find the critical t value.*
**Attempted Solution:**
The user input the value **1.7171**, which was flagged as incorrect.
**Action Button:**
- **Submit Question**
**Explanation:**
In statistics, the critical t value is derived from the t distribution and depends on the desired confidence level and the degrees of freedom, which is computed as the sample size minus one. For a sample size of 23, the degrees of freedom would be 22. At a 95% confidence level, you would consult a t-table or use statistical software to find the accurate t value corresponding to 22 degrees of freedom. If the provided solution is marked incorrect, rechecking the calculation or consulting a different t distribution source might be necessary.
