1. A student was asked to find a 95% confidence interval for widget width using data from a random sample of size n = 16. Which of the following is a correct interpretation of the interval 12.6 < μ < 32.3? Check all that are correct.
a) There is a 95% chance that the mean of a sample of 16 widgets will be between 12.6 and 32.3.
b) There is a 95% chance that the mean of the population is between 12.6 and 32.3.
c) With 95% confidence, the mean width of a randomly selected widget will be between 12.6 and 32.3.
d) With 95% confidence, the mean width of all widgets is between 12.6 and 32.3.
e) The mean width of all widgets is between 12.6 and 32.3, 95% of the time.
f) We know this is true because the mean of our sample is between 12.6 and 32.3.
