No-cfc and green cool manufacture air conditioners. no-cfc claims that their air conditioners cool faster than green cool air conditioners. an air conditioning magazine decided to test no-cfc's claim. they randomly tested five no-cfc air conditioners at their dallas office and five green cool air conditioners at their phoenix office. all of the air conditioners had the same specifications, were set to auto cooling mode, and were installed in rooms with the same amount of space to be cooled. after observing the cooling effect of each air conditioner, the magazine reported that the average time it takes for a no-cfc air conditioner to reduce the room temperature by 3°f was 10 minutes, and the average time it takes for a green cool air conditioner to reduce the room temperature by 3°f was 12 minutes. given the magazine's data collection method and report, what conclusion can be made?
