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 13.5 < μ < 23.1? A)There is a 90% probability that the mean of a sample of 15 widgets will be between 13.5 and 23.1. B) With 90% confidence, the mean width of all widgets is between 13.5 and 23.1. C) With 90% confidence, the mean width of a randomly selected widget will be between 13.5 and 23.1. D) The mean width of all widgets is between 13.5 and 23.1, 90% of the time. We know this is true because the mean of our sample is between 13.5 and 23.1. E) There is a 90% probability that the mean of the population is between 13.5 and 23.1.
