A student was asked to find a 98% 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 < µ< 26.3? Check all that are correct. There is a 98% chance that the mean of a sample of 17 widgets will be between 14.9 and 26.3. The mean width of all widgets is between 14.9 and 26.3, 98% of the time. We know this is true because the mean of our sample is between 14.9 and 26.3. With 98% confidence, the mean width of all widgets is between 14.9 and 26.3. With 98% confidence, the mean width of a randomly selected widget will be between 14.9 and 26.3. There is a 98% chance that the mean of the population is between 14.9 and 26.3.
