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 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 -37.3 sec<μ< 245.8 sec, what should we conclude about the claim? 61 77 15 560 52 0 209 44 The confidence level should be %. (Type an integer or a decimal.
