A student was asked to find a 95% confidence interval for widget width using data from a random sample of size n = 28. Which of the following is a correct interpretation of the interval 11.9 < μ < 22?

With 95% confidence, the mean width of all widgets is between 11.9 and 22.
With 95% confidence, the width of a randomly selected widget will be between 11.9 and 22.
There is a 95% chance that the mean of a sample of 28 widgets will be between 11.9 and 22.
The width of all widgets is between 11.9 and 22, 95% of the time. We know this is true because the mean of our sample is between 11.9 and 22.
There is a 95% chance that the width of the widget is between 11.9 and 22.
