A student was asked to find a 90% 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
(13.9,21.8)?
With 90% confidence, the mean width of a randomly selected
widget will be between 13.9 and 21.8.
There is a 90% chance that the mean of a sample of 16 widgets
will be between 13.9 and 21.8.
We are 90% confident the mean width of all widgets is between
13.9 and 21.8.
There is a 90% chance that the mean of the population is between
13.9 and 21.8.
The mean width of all widgets is between 13.9 and 21.8, 90% of
the time.
We know this is true because the mean of our sample is between
13.9 and 21.8.
