A bottled water company bottles varying sizes of water, from 8-ounce to 1-gallon containers. The company has
determined that the mean quantity in their 20-ounce bottles is 20.8 ounces with a standard deviation of 0.6 ounces. The
bottling plant manager believes his machines are overfilling the bottles. A random sample of 30 bottles is taken, and the
mean number of ounces of water is recorded. Which of the following values of the mean of the sample is most likely to
occur if the true mean number of ounces is 20.8?
19.8
20.4
20.9
21.2

No, since a sample mean of 20.9 or more occurred 19 out of 100 times, there is insufficient evidence that the true mean ounces of the bottles of water is greater than 20.8
