Enter your answer as an open-interval (i.e., parentheses) accurate to two decimalplaces.99% C.I. = A student was asked to find a 98% confidence interval for widget width using data from a randomsample of size n = 17. Which of the following is a correct interpretation of the interval 14.9 < µ<26.3?Check all that are correct.There is a 98% chance that the mean of a sample of 17 widgets will be between 14.9 and 26.3.The mean width of all widgets is between 14.9 and 26.3, 98% of the time. We know this is truebecause the mean of our sample is between 14.9 and 26.3.With 98% confidence, the mean width of all widgets is between 14.9 and 26.3.With 98% confidence, the mean width of a randomly selected widget will be between 14.9 and26.3.There is a 98% chance that the mean of the population is between 14.9 and 26.3.
