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.

When ever a percentage confidence interval is constructed, the answers that we have simply implies that we are x% sure ( Where x is the confidence level) that our value for interval is between the ones that we just got.

Going by our question, it implies that we are 95% sure that an average students work between 4.63 and 12.63 hours in a week

Using the interpretation of a confidence interval, it is found that the correct option is:

We are 95% confident that the population mean time that college students work is between 4.63 and 12.63 hours a week.

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this problem, the 95% confidence interval for the number of hours students work per week is (4.63, 12.63), thus, the correct interpretation is:

We are 95% confident that the population mean time that college students work is between 4.63 and 12.63 hours a week.
