TEACHER Weatherwae is a magatine pubiished by the American Meteorological Society. One issue grves a rating system used to classify Noreaster storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) oft fived cement piers. Suppose that a reading of 40 waves showed an average wave height of 16.7 feet. Previous studies of severe storms indicate that 3.5 feet. Does this information suggest that the sterm is (perhaps temporarily) increasing above the severe rating? Use aw0.01.
