A student was asked to find a 90% confidence interval for widget width using data from a random sample of size n = 25. Which of the following is a correct interpretation of the interval 12.1 < p < 24.2? Check all that are correct. The mean width of all widgets is between 12.1 and 24.2, 90% of the time. We know this is true because the mean of our sample is between 12.1 and 24.2. With 90% confidence, the mean width of a randomly selected widget will be between 12.1 and 24.2. There is a 90% chance that the mean of a sample of 25 widgets will be between 12.1 and 24.2. O With 90% confidence, the mean width of all widgets is between 12.1 and 24.2. O There is a 90% chance that the mean of the population is between 12.1 and 24.2.

A student was asked to find a 90% confidence interval for widget width using data from a random sample of
size n = 25. Which of the following is a correct interpretation of the interval 12.1 < p < 24.2?
Check all that are correct.
The mean width of all widgets is between 12.1 and 24.2, 90% of the time. We know this is true
because the mean of our sample is between 12.1 and 24.2.
With 90% confidence, the mean width of a randomly selected widget will be between 12.1 and 24.2.
There is a 90% chance that the mean of a sample of 25 widgets will be between 12.1 and 24.2.
O With 90% confidence, the mean width of all widgets is between 12.1 and 24.2.
O There is a 90% chance that the mean of the population is between 12.1 and 24.2.
