A student was asked to find a 98% confidence interval for widget width using data from a random sample of size n-24. Which of the following is a correct interpretation of the interval 12 < μ < 32.8? Check all that are correct O With 98% confidence, the mean width of a randomly selected widget will be between 12 and 32.8. O There is a 98% chance that the mean of the population is between 12 and 32.8. O With 98% confidence, the mean width of all widgets is between 12 and 32.8. O There is a 98% chance that the mean of a sample of 24 widgets will be between 12 and 32.8. O The mean width of all widgets is between 12 and 32.8, 98% of the time. We know this is true because the mean of our sample is between 12 and 32.8.
