Question
**Title: Calculating a T-Score for a Confidence Interval** --- **Determine the t-score for a 99% confidence interval for a population mean from a sample of size 8.** - \( t = \) [Input field] [Three decimal accuracy] --- **Explanation:** To calculate the t-score for a 99% confidence interval when given a sample size of 8, you can use the t-distribution table. Since the sample size is 8, you have 7 degrees of freedom (sample size - 1). Look for the t-value corresponding to 99% confidence level and 7 degrees of freedom. This will typically involve using statistical software or a t-table that provides values for different levels of confidence and degrees of freedom. **Note:** Ensure to round the t-value to three decimal places for accuracy.
