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 24.2 secless thanmuless than184.7 sec, what should we conclude about the claim?
