A study reports that college students work, on average, between 4.63 and 12.63 hours a week, with confidence coefficient .95. Which of the following statements are correct? MARK ALL THAT ARE TRUE. There are four correct answers. You must mark them all to get credit. Group of answer choices The interval was produced by a technique that captures mu 95% of the time. 95% of all college students work between 4.63 and 12.63 hours a week. 95% of all samples will have x-bar between 4.63 and 12.63. The probability that mu is between 4.63 and 12.63 is .95. 95% of samples will produce intervals that contain mu. The probability that mu is included in a 95% CI is 0.95. We are 95% confident that the population mean time that college students work is between 4.63 and 12.63 hours a week.
