A student was asked to find a 90% 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 13.2 < μ < 33.5? Check all that are correct.
A) There is a 90% chance that the mean of a sample of 15 widgets will be between 13.2 and 33.5.
B) There is a 90% chance that the mean of the population is between 13.2 and 33.5.
C) The mean width of all widgets is between 13.2 and 33.5, 90% of the time. We know this is true because the mean of our sample is between 13.2 and 33.5.
D) With 90% confidence, the mean width of all widgets is between 13.2 and 33.5.
E) With 90% confidence, the mean width of a randomly selected widget will be between 13.2 and 33.5.
