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 23.6 secless thanmuless than182.9 sec, what should we conclude about the claim? 85 14 541 51 0 53 216 44 174 0 2 59

Suppose that you have a sample size n = 100 with mean x = 5 and standard deviation s = 2, and that you are to construct a confidence interval for the population mean \mu μ . if, after you obtain the confidence interval, you find it to be too wide, which of the following remedial steps can you take to reduce the width of the confidence interval? a. to construct a 90% confidence interval instead of a 95% one. b. to construct a 99% confidence interval instead of a 95% one. c. to re-do the 95% confidence interval with only a half pf the sample data.
