A student was asked to find a 98% confidence interval for widget width using data from a random sample of size n = 22. Which of the following is a correct interpretation of the interval 10.2 < μ< 29.7? Check all that are correct. There is a 98% chance that the mean of a sample of 22 widgets will be between 10.2 and 29.7. With 98% confidence, the mean width of all widgets is between 10.2 and 29.7. The mean width of all widgets is between 10.2 and 29.7, 98% of the time. We know this is true because the mean of our sample is between 10.2 and 29.7. There is a 98% chance that the mean of the population is between 10.2 and 29.7. With 98% confidence, the mean width of a randomly selected widget will be between 10.2 and 29.7.

Question
A student was asked to find a 98% confidence interval for widget width using data from a random sample of
size n = 22. Which of the following is a correct interpretation of the interval 10.2 < µ < 29.7?
Check all that are correct.
There is a 98% chance that the mean of a sample of 22 widgets will be between 10.2 and 29.7.
With 98% confidence, the mean width of all widgets is between 10.2 and 29.7.
The mean width of all widgets is between 10.2 and 29.7, 98% of the time. We know this is true
because the mean of our sample is between 10.2 and 29.7.
There is a 98% chance that the mean of the population is between 10.2 and 29.7.
With 98% confidence, the mean width of a randomly selected widget will be between 10.2 and 29.7.
