A student was asked to find a 95% confidence interval for widget width using data from a random sample of size n = 23. Which of the following is a correct interpretation of the interval 12.3 < μ < 25?Check all that are correct.There is a 95% chance that the mean of a sample of 23 widgets will be between 12.3 and 25.There is a 95% chance that the mean of the population is between 12.3 and 25.The mean width of all widgets is between 12.3 and 25, 95% of the time. We know this is true because the mean of our sample is between 12.3 and 25.With 95% confidence, the mean width of a randomly selected widget will be between 12.3 and 25.With 95% confidence, the mean width of all widgets is between 12.3 and 25.
