Assume you want to know whether the prices of meatballs change during the christmas holiday season. You therefore go to 14 meat-stores before the holiday to check the prices of one kilo of meatballs. In the middle of the holidays, you walk around to the same 14 meat-stores and check the prices again. The results of your research is seen in the table in the picture below. Make a hypothesis test, where you test whether the prices have changed between the two surveys. Use ? = 0.05
