A student was asked to find a 90% confidence interval for widget width using data from a random sample of size n = 27. Which of the following is a correct interpretation of the interval 10.2 < μ < 20.6?
Check all that are correct.
- With 90% confidence, the mean width of a randomly selected widget will be between 10.2 and 20.6.
- With 90% confidence, the mean width of all widgets is between 10.2 and 20.6.
- There is a 90% chance that the mean of the population is between 10.2 and 20.6.
- The mean width of all widgets is between 10.2 and 20.6, 90% of the time. We know this is true because the mean of our sample is between 10.2 and 20.6.
- There is a 90% chance that the mean of a sample of 27 widgets will be between 10.2 and 20.6.
