interpretation of the interval 11.9 < μ < 20.8? Check all that are correct. a. There is 90% chance that the mean of the population is between 11.9 and 20.8. b. With 90% confidence, the mean width of all widgets is between 11.9 and 20.8. c. With 90% confidence, the mean width of a randomly selected widget will be between 11.9 and 20.8. d. The mean width of all widgets is between 11.9 and 20.8, 90% of the time. We know this is true because the mean of our sample is between 11.9 and 20.8. e. There is a 90% chance that the mean of a sample of 26 widgets will be between 11.9 and 20.8
A student was asked to find a 90% confidence interval for widget width using data from a random sample of size n = 26. Which of the following is a correct interpretation of the interval 11.9 < μ < 20.8?
Check all that are correct.
a. There is 90% chance that the
b. With 90% confidence, the mean width of all widgets is between 11.9 and 20.8.
c. With 90% confidence, the mean width of a randomly selected widget will be between 11.9 and 20.8.
d. The mean width of all widgets is between 11.9 and 20.8, 90% of the time. We know this is true because the mean of our sample is between 11.9 and 20.8.
e. There is a 90% chance that the mean of a sample of 26 widgets will be between 11.9 and 20.8
