Twelve different video games showing violence were observed. The duration times of violence were recorded, with the times (seconds) listed below. Assume that these sample data are used with a 0.01 significance level in a test of the claim that the population mean is greater than 90 sec. If we want to construct a confidence interval to be used for testing that claim, what confidence level should be used for a confidence interval? If the confidence interval is found to be - 44.4 sec

**Observation of Violent Content in Video Games** In a study, twelve different video games showcasing violence were analyzed. The duration of violent content was measured and recorded in seconds as follows: 88, 15, 611, 52, 0, 57, 222, 41, 173, 0, 2, 59 seconds. **Statistical Analysis:** - **Objective**: To test the claim that the population mean duration of violence in these video games is greater than 90 seconds. - **Significance Level**: The data is tested at a 0.01 significance level. - **Confidence Interval**: A specific confidence interval is used to assess this claim. If a confidence interval calculated for the mean is found to be \(-44.4 \, \text{sec} < \mu < 264.4 \, \text{sec}\), the question arises: **Conclusion Query**: What confidence level is appropriate for this interval? Determine the confidence level at which this interval supports or disputes the original claim. - **Answer Format**: The confidence level should be expressed in percentage, as an integer or decimal (no rounding).
