- 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 ? = 0.05arrow_forwardPlease use the five steps in hypothesis testing. (a) Meteorology: Storms Weatherwise is a magazine published by the American Meteorological Society. One issuegives a rating system used to classify Northeaster storms that frequently hit New England and can cause muchdamage near the ocean. A severe storm has an average peak wave height of μ=16.4 ft for waves hitting the shore. Suppose that a Northeaster is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 36 waves showed on average wave height of x̄=17.3 ft. Previous studies of severe storms indicate that σ=3.5 ft. . Does this information suggest that the storm is perhaps temporarily increasing above the severe rating?
