Twelve different video games showing
were observed. The duration times of
were recorded, with the times (seconds) listed below. Assume that these sample data are used with a
significance level in a test of the claim that the population mean is greater than
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
sec
sec, what should we conclude about the claim?
