3. [-/4.08 Points] DETAILS BBUNDERSTAT12 8.2.011. MY NOTES ASK YOUR TEACHER fatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify r'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average ak wave height of # = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class ing. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 34 ves showed an average wave height of x = 16.7 feet. Previous studies of severe storms indicate that o = 3.5 feet. Does this ormation suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use a = 0.01. (@) What is the level of significance? State the null and alternate hypotheses. OH: # > 16.4 ft; H : M = 16.4 ft O Ho: M = 16.4 ft; Hj: M > 16.4 ft O Ho: M 0.250 O 0.100
