Suppose that a random sample of 42 bottles of a particular brand of wine is selected and the alcohol content of each bottle is determined. Let μ denote the average alcohol content for the population of all bottles of the brand under study. Suppose that the resulting 95% confidence interval is (10.8,12.4). Which of the following is true when using the same data set. (Select all that apply.) The true mean μ is between 10.8 and 12.490% of the time. A 90% confidence interval for μ will be an interval that is contained in (10.8,12.4). A 90\% confidence interval will end up being narrower. A 90\% confidence interval for μ will be an interval that contains the interval (10.8,12.4).
