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 seconds. 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 18.8 seconds < mu < 196.9 seconds, what should we conclude about the claim?
