8.3.4 Question Help 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 0.10 significance level in a test of the claim that the population mean is greater than 75 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 20.1 sec<μ<197.8 sec, what should we conclude about the claim?
