A student was asked to find a 98% confidence interval for widget width using data from a random sample of size n = 15. Which of the following is a correct interpretation of the interval 14.7 < μ < 33.2?Check all that are correct.With 98% confidence, the mean width of a randomly selected widget will be between 14.7 and 33.2.98% of all the widgets have a width between 14.7 and 33.2.With 98% confidence, the mean width of all widgets is between 14.7 and 33.2.There is a 98% chance that the mean of a sample of 15 widgets will be between 14.7 and 33.2.

Solution:-Given that,Confidence level = 98% = 0.98n = 15
