Twelve different video games showing alcohol use were observed. The duration times of alcohol use were recorded, with the times (seconds) listed below. Assume that these sample data are used with a 0.05 significance level in a test of the claim that the population mean is greater than 80 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 2.9 sec<μ<210.9 sec, what should we conclude about the claim? 83 14 577 49 0 58 214 40 188 0 2 58 The confidence interval should be __% (type an integer or a decimal. Do not round.) What should we conclude about the claim? The given confidence interval (contains/does not contain) the value of 75 sec, so there (is/is not) sufficient evidence to support the claim that the mean is greater than 75 sec.

What should we conclude about the claim?
The given confidence interval (contains/does not contain) the value of 75 sec, so there (is/is not) sufficient evidence to support the claim that the mean is greater than 75 sec.
