Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of u = 16.4 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) off fixed cement piers. Suppose that a reading of 36 waves showed an average wave height of x = 17.3 feet. Previous studies of severe storms indicate that . = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use a = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. o Ho: M 16.4 ft; H1: M = 16.4 ft o Ho: M = 16.4 ft; H1: u # 16.4 ft o Ho: M = 16.4 ft; H1: M > 16.4 ft o Ho: M = 16.4 ft; H1: M 0.250 0.100
