Twelve different video games showing drug use drug use were observed. the duration times of drug use drug use were recorded, with the times (seconds) listed below. assume that these sample data are used with a 0.05 0.05 significance level in a test of the claim that the population mean is greater than 90 90 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 negative 0.6 −0.6 sec less than < mu μ less than < 217.1 217.1 sec, what should we conclude about the claim?
