An article in Fire Technology investigated two different foam-expanding agents that can be used in the nozzles of fire fighti equipment. A random sample of five observation with an aqueous film-forming foam had a sample mean of 4.7 and a standard deviation of 0.6. A random sample of five observations with alcohol-type concentrates had a sample mean of 6.9 and a standard deviation of 0.8. What type of hypothesis test would be most appropriate to determine if there is a difference in the mean foam expansion? O 2 Sample Z-Test O 2 Sample F-Test O Answer not here O 2 Sample T-Test
