A student was asked to find a 98% confidence interval for widget width using data from a random sample of size n = 15. Which of the following is a correct interpretation of the interval 12.7 < μ< 34.2? Check all that are correct. The mean width of all widgets is between 12.7 and 34.2, 98% of the time. We know this is true because the mean of our sample is between 12.7 and 34.2. There is a 98% chance that the mean of the population is between 12.7 and 34.2. There is a 98% chance that the mean of a sample of 15 widgets will be between 12.7 and 34.2. With 98% confidence, the mean width of all widgets is between 12.7 and 34.2. With 98% confidence, the mean width of a randomly selected widget will be between 12.7 and 34.2.
