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 80 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 −34.0 sec<μ<242.0 sec, what should we conclude about the claim?
