Question: The Prescott Bottling Company, producers of the best selling (in Peoria) Fuzzy Swamp Water Soda (tastes like the clean Florida Everglades swamp water) uses dispensing machines that allow the customer to get Swamp Water Soda from the machine in a cup with ice. When the machines are running properly, the average number of fluid ounces in the cup should be 14. Periodically the machines need to be tested to make sure that they have not gone out of adjustment. To do this six cups are filled by the machine and a technician ( who is the unemployed brother-in-law of the owner ) carefully measures the volume in each cup. In one such test the following data were observed: (See next page)

Based on these sample data, which of the following is true if the level of significance is .05?

a. The null hypothesis cannot be rejected since the test statistic is approximately t = 1.00, which is not in the rejection region

b. The null hypothesis can be rejected since the sample mean is greater than 14.

c. The null can be rejected because the majority of the sample values exceed 14.

d. No conclusion can be reached about the status of the machine based on a sample size of only six cups.
