A student was asked to find a 99% confidence interval for widget width using data from a random sample of size n = 27. Which of the following is a correct interpretation of the interval 12.1 < μ < 25.3? Check all that are correct. With 99% confidence, the mean width of a randomly selected widget will be between 12.1 and 25.3. There is a 99% chance that the mean of the population is between 12.1 and 25.3. With 99% confidence, the mean width of all widgets is between 12.1 and 25.3. There is a 99% chance that the mean of a sample of 27 widgets will be between 12.1 and 25.3. The mean width of all widgets is between 12.1 and 25.3, 99% of the time. We know this is true because the mean of our sample is between 12.1 and 25.3.

A student was asked to find a 99% confidence interval for widget width using data from a random sample of size n = 27. Which of the following is a correct interpretation of the interval 12.1 < μ < 25.3?
Check all that are correct.
- With 99% confidence, the
mean width of a randomly selected widget will be between 12.1 and 25.3. - There is a 99% chance that the mean of the population is between 12.1 and 25.3.
- With 99% confidence, the mean width of all widgets is between 12.1 and 25.3.
- There is a 99% chance that the mean of a sample of 27 widgets will be between 12.1 and 25.3.
- The mean width of all widgets is between 12.1 and 25.3, 99% of the time. We know this is true because the mean of our sample is between 12.1 and 25.3.
