A student was asked to find a 99% 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 13.9 < μ < 27.1? 

Check all that are correct below.

a) With 99% confidence, the mean width of all widgets is between 13.9 and 27.1.

b) There is a 99% chance that the mean of a sample of 20 widgets will be between 13.9 and 27.1.

c) With 99% confidence, the mean width of a randomly selected widget will be between 13.9 and 27.1.

d) The mean width of all widgets is between 13.9 and 27.1, 99% of the time. We know this is true because the mean of our sample is between 13.9 and 27.1.

e) There is a 99% chance that the mean of the population is between 13.9 and 27.1.
