QUESTION 27

Suppose that a random sample of 75 bottles of a particular brand of craft beer is selected and the alcohol content of each bottle is determined. Letdenote the average alcohol content for the population of all bottles of the brand under study. Suppose that the sample of 75 results in a 95% confidence interval forof (6.2, 8.3). Which of the following is the correct interpretation of the interval?

1. There is a 95% chance that the sample mean is between 6.2 and 8.3.
2. There is a 95% chance thatis between 6.2 and 8.3
3. 95% of all bottles have alcohol content between 6.2 and 8.3.
4. The method used to get the interval from 6.2 to 8.3, when used on infinitely many random samples of the same size from the same population, produces intervals which include the population mean in 95% of the intervals
