8.2 Hypothesis Test using Z
Nor'easter storms that frequently hit New England can cause much damage near the ocean. A severe storm has an average peak wave height of??= 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 38 waves showed an average wave height of??= 18.3 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??= 0.10.?Solve the problem using both the critical region method (i.e. traditional method) and the?P-value method. (Round your answers to two decimal places for the test statistic and the critical value. Round your answer to four decimal places for the?P-value.)Bypass any proctored exams 2025.
