Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used lo 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 μ=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 xˉ=17.3 feets. Previous studies of severe storms indicate that σ=3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use the 0.01 level of significance and the P - Value method
a.) Hypotheses (5 points):
H0⋅μ=16.4 feet Ha⋅μ>16.4 feet Levelot S Sandicance: α=0.01
Sample sie n=36z=3.5/60.9=0.58330.9≈1.51nP(z>1.54)≈0.0618
d.) Decision ( 5 points): Since the P-value 0.0618 is greater than the sio level a=0.01, we fail to reject the null hypo
