A student was asked to find a 95% confidence interval for widget width using data from a random sample of size n = 20. Which of the following is a correct interpretation of the interval 10 < µ < 29.9? Check all that are correct. The mean width of all widgets is between 10 and 29.9, 95% of the time. We know this is true because the mean of our sample is between 10 and 29.9. With 95% confidence, the mean width of all widgets is between 10 and 29.9. There is a 95% chance that the mean of the population is between 10 and 29.9. With 95% confidence, the mean width of a randomly selected widget will be between 10 and 29.9. There is a 95% chance that the mean of a sample of 20 widgets will be between 10 and 29.9.
