A student was asked to find a 99% confidence interval for widget width using data from a random sample of size n = 17. Which of the following is a correct interpretation of the interval 14.9 < p < 25.4? Check all that are correct. The mean width of all widgets is between 14.9 and 25.4, 99% of the time. We know this is true because the mean of our sample is between 14.9 and 25.4. With 99% confidence, the mean width of all widgets is between 14.9 and 25.4. With 99% confidence, the mean width of a randomly selected widget will be between 14.9 and 25.4. There is a 99% chance that the mean of a sample of 17 widgets will be between 14.9 and 25.4. There is a 99% chance that the mean of the population is between 14.9 and 25.4.

A student was asked to find a 99% confidence interval for widget width using data from a random sample of
size n = 17. Which of the following is a correct interpretation of the interval 14.9 < p < 25.4?
Check all that are correct.
The mean width of all widgets is between 14.9 and 25.4, 99% of the time. We know this is true
because the mean of our sample is between 14.9 and 25.4.
With 99% confidence, the mean width of all widgets is between 14.9 and 25.4.
With 99% confidence, the mean width of a randomly selected widget will be between 14.9 and 25.4.
There is a 99% chance that the mean of a sample of 17 widgets will be between 14.9 and 25.4.
There is a 99% chance that the mean of the population is between 14.9 and 25.4.
