A student was asked to find a 90% 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 13.7 < < 25.5?

Check all that are correct.

• The mean width of all widgets is between 13.7 and 25.5, 90% of the time. We know this is true because the mean of our sample is between 13.7 and 25.5.
• With 90% confidence, the mean width of a randomly selected widget will be between 13.7 and 25.5.
• There is a 90% chance that the mean of a sample of 22 widgets will be between 13.7 and 25.5.
• With 90% confidence, the mean width of all widgets is between 13.7 and 25.5.
• There is a 90% chance that the mean of the population is between 13.7 and 25.5.
