A student was asked to find a 95% confidence interval for widget width using data from a random sample of size n = 27. Which of the following is a correct interpretation of the interval 14.9 < μ < 31.8? Check all that are correct. With 95% confidence, the mean width of a randomly selected widget will be between 14.9 and 31.8. The mean width of all widgets is between 14.9 and 31.8, 95% of the time. We know this is true because the mean of our sample is between 14.9 and 31.8. There is a 95% chance that the mean of a sample of 27 widgets will be between 14.9 and 31.8. With 95% confidence, the mean width of all widgets is between 14.9 and 31.8. There is a 95% chance that the mean of the population is between 14.9 and 31.8.
